Jump balls are a unique feature of basketball, occurring when a defender legally forces an opponent to commit a violation, resulting in a situation where neither team has control of the ball. This often happens during a try for a goal or when players are scrambling for the ball in a congested area. Jump balls are also called when both players are holding the ball simultaneously, or when a defender has their hand atop the ball during a block. The jump ball rule states that if a personal foul occurs before either team gains possession, it is ruled as a loose ball foul, with neither the game clock nor the shot clock started. The violation rules are clear that the ball is then awarded to the opposing team on the sideline nearest the violation.
| Characteristics | Values |
|---|---|
| Jump Ball Occurrence | When a defender legally forces an offensive player to commit a violation, or when a defender blocks the shot and the offensive player lands with the ball still in their hands. |
| Possession | If the violation or foul occurs prior to the ball being legally tapped, neither team obtains possession and the game clock or shot clock is not started. |
| Fouls | During a jump ball, a personal foul committed prior to either team obtaining possession is ruled a "loose ball" foul. |
| Violation by Defense | If the defense violates while the ball is in play, the offensive team retains possession on the sideline nearest the spot of the violation but no nearer the baseline than the foul line extended. |
| Violation by Offense | If the violation occurs during a throw-in, the opposing team retains possession at the spot of the original throw-in with all privileges. |
| Invalid Jump Ball Calls | Jump ball should not be called when only one player is holding the ball, even if the defender has their hand on top of the ball during the block. |
| Valid Jump Ball Calls | Jump ball is called when two players are holding onto the ball at the same time in a scramble situation, or when referees cannot make a consensus call. |

Jump ball rules
Jump balls are a common way to restart play in basketball when it is unclear which team should gain possession of the ball. A jump ball typically occurs when opposing players gain simultaneous possession of the ball, or when a referee is unsure as to who last touched the ball before it went out of bounds.
During a jump ball, two players face each other and attempt to gain possession of the ball after it is tossed into the air by the referee. The players must try to tap the ball to a teammate, without committing a violation. If the ball is tapped directly out of bounds, the non-offending team will receive the ball for an inbounds pass at the spot where it went out of play.
Jump balls can also be called when a defender legally forces an offensive player to commit a violation, such as when a defender blocks a shot and the offensive player lands with the ball still in their hands. In this case, the jump ball ensures that the defensive player is rewarded for their block, without giving possession back to the offensive team.
There are several rules that apply specifically to jump balls. Firstly, any personal foul committed before either team gains possession of the ball shall be ruled a "loose ball" foul. Secondly, if the violation or foul occurs before the ball is tapped, neither the game clock nor the shot clock will be started. Finally, if there is a violation by both teams, or if the official makes a bad toss, the jump ball will be repeated with the same players.

Violation scenarios
A jump ball violation in basketball can occur in a variety of scenarios, often during crucial moments of the game. Here are some examples:
Scenario 1: Block and Possession
A jump ball violation may be called when a defender legally blocks a shot, but the offensive player still has possession of the ball for a brief moment during the block. This scenario can lead to a dispute over whether it should be ruled as a jump ball or a turnover, with some arguing that a jump ball does not guarantee possession for the defending team.
Scenario 2: Scramble for Possession
Another situation where a jump ball violation may occur is when two players from opposing teams are scrambling for possession of the ball. If they both have a grip on the ball simultaneously, a jump ball violation may be called to resolve the situation fairly. However, some fans and commentators argue that this call can disrupt the flow of the game and that referees should make more definitive calls to maintain momentum.
Scenario 3: Tapping the Ball
During a jump ball, if a player from either team (jumper A1) taps or tips the tossed ball directly out of bounds without any non-jumpers touching it, it is considered a violation. In this case, the violating team concedes possession to the opposing team for an inbounds pass at the spot where the ball went out of bounds.
Scenario 4: Eight-Second Violation
A jump ball violation can also occur if a team maintains possession of the ball in their backcourt for more than 8 consecutive seconds. This violation results in the loss of the ball, and it is awarded to the opposing team at the midcourt line. However, exceptions can be made if the defending team commits certain violations, such as kicking or punching the ball, resulting in a new 8-second count.
Scenario 5: Pivoting and Dribbling
Jump ball violations can also occur due to violations of pivoting and dribbling rules. For example, if a player jumps with both feet while dribbling, they must release the ball before either foot touches the floor again. Violating these rules can result in a jump ball situation or a turnover, depending on the context.

Possession and penalties
If a violation occurs during a jump ball, the ball is awarded to the opposing team at the midcourt line. This penalty also applies if a player swings their elbows excessively or vigorously when a defensive player is nearby and the offensive player has the ball.
Additionally, there are rules regarding possession and penalties in other situations. If a violation occurs by the defence while the ball is in play, the offensive team retains possession on the sideline nearest the spot of the violation. However, if the violation occurs during a throw-in, the opposing team gains possession at the spot of the original throw-in.
A team cannot continuously possess the ball in its backcourt for more than eight consecutive seconds. Exceptions to this rule include defensive actions such as kicking or punching the ball, personal or technical fouls, or delay-of-game warnings, which reset the eight-second count. Other exceptions include gaining control of a jump ball in the backcourt and specific throw-in scenarios in the final two minutes of the fourth quarter or any overtime period. Violation of this rule results in the loss of ball possession, with the ball awarded to the opposing team at the midcourt line.

Pivoting and dribbling
When a player catches the ball, they may stop and establish a pivot foot. If both feet are off the ground, the first foot to touch the floor when landing becomes the pivot foot. If a player lands with both feet simultaneously, neither can be the pivot foot. When a player is dribbling, they must establish a pivot foot before they can pass or shoot. The pivot foot cannot slide or move before the ball is released, or it is considered travelling.
When a player receives the ball, they must dribble before taking their second step. If a player is moving when they receive the ball, they must dribble before their next step. If a player jumps with both feet, they must release the ball before either foot touches the floor. A player who lands with one foot first may only pivot using that foot. If a player jumps off one foot, they may land with both feet simultaneously for the second step, but they may not pivot with either foot.
Pivoting is a fundamental skill in basketball, allowing players to create space, protect the ball, and set up shots. It is a key part of footwork training for young players, helping them to understand movement and balance.

Blocks and fouls
While a jump ball is not a block or a foul, it is important to understand what it is, as it is often used to determine possession in the event of a violation or foul. A jump ball occurs when the referee tosses the ball vertically between two opposing players, who jump and attempt to tap it to a teammate.
Now, onto blocks and fouls. A block is when a defender physically blocks their opponent's path without first getting into a legal guarding position. To be in a legal guarding position, the defender must face their opponent directly with their feet firmly on the ground, and they must not lean into the offensive player. A block is not a foul, and it is legal as long as the defender is in a legal guarding position.
A foul, on the other hand, is a violation of the rules that is called by a referee. There are many types of fouls in basketball, and they can be called on either the offensive or defensive players. Here are some common types of fouls:
- Holding foul: When a player limits the movement of their opponent.
- Reaching foul: When a defender tries to steal the ball but makes contact with their opponent.
- Hand-checking: When a player uses their hands illegally to slow or impede an opponent.
- Technical foul: When a player slaps or strikes the backboard with force, or a defender breaks the boundary plane and makes contact with or fouls the inbounding player.
- Personal foul: When a player commits a foul against another player. This can be further categorized into offensive and defensive fouls.
- Intentional foul: When the defence commits a foul on purpose, hoping to stop the clock or gain possession.
It is important to note that every foul is a violation, but not every violation is a foul. Violations are often related to time restrictions, such as shot clock violations, or procedural errors, such as stepping out of bounds during a throw-in.
