A held ball stops the tie-up. Alternating possession decides the restart.

How officials handle a tie-up

1. Decide whether there is real shared control, a trapped ball, a foul, a travel, or only a defender briefly touching the ball.
2. If there is illegal contact before the tie-up is established, apply the foul rule instead of calling a held ball.
3. If the ball is truly held or otherwise neutral under the active rulebook, stop play before the struggle becomes unsafe or excessively rough.
4. Check whether the competition uses an alternating-possession throw-in or an actual jump ball for that situation.
5. Administer the restart at the proper spot, then change or preserve the arrow according to when the alternating-possession opportunity legally ends.

What counts as a held ball

A held ball usually means two opponents have one or both hands so firmly on the ball that neither can gain sole possession without excessive force. Officials are not looking for a defender simply brushing the ball, slapping down at it, or momentarily pinning it for a fraction of a second. The question is whether both players have meaningful, simultaneous control.

Some rulebooks also treat specific trapped-ball situations as jump-ball or alternating-possession plays. Examples can include a ball lodged between the ring and backboard, simultaneous out-of-bounds touches, or a situation where the officials cannot identify a clear last touch. The details vary, so the active competition's restart rule controls.

What alternating possession means

Alternating possession is a rotation system. Instead of making players jump for the ball after every held-ball situation, the table or officials keep an arrow that points to the team entitled to the next alternating-possession throw-in. After that team uses the opportunity, the arrow points the other way for the next qualifying situation.

In many arrow systems, the opening jump ball establishes the first arrow. The team that does not gain first control after the opening tap is awarded the first alternating-possession opportunity. Later tied-possession situations then alternate between the teams rather than being decided by who is stronger in the tie-up.

How the throw-in works

When the arrow applies, the restart is normally a throw-in for the team indicated by the arrow. The throw-in spot depends on where play stopped and the rulebook's placement rule. The ball then follows ordinary throw-in requirements, including boundary restrictions, defender restrictions, and any applicable count covered in the inbound pass and five-second rules.

The arrow does not change merely because the whistle sounded or because an official pointed a direction. It changes when the alternating-possession throw-in is completed or otherwise used under that rulebook. That timing matters when a foul, violation, timeout, or administrative correction happens before the ball is legally put in play.

When the arrow changes

The common rule is that the arrow changes after the alternating-possession throw-in legally ends. In practical terms, that often means the throw-in pass is legally touched by a player on the court, or the throw-in ends through a violation that counts as using the team's alternating-possession opportunity.

The hardest situations occur before the throw-in is completed. If the team awarded the arrow violates the throw-in rule, many competitions treat that team as having used its opportunity and then reverse the arrow. If the opponent fouls or violates before the throw-in is completed, the original team may keep the arrow because its opportunity was interrupted. Officials have to apply the exact rulebook language rather than a one-size-fits-all shortcut.

Common alternating-possession plays

• Held balls: two opponents tie up the ball with firm simultaneous control.
• Simultaneous out of bounds: opponents touch the ball at the same time before it goes out, or officials cannot determine a last touch.
• Ball lodged or trapped: the ball becomes stuck in a place the rulebook treats as neutral rather than awarding it by last touch.
• Simultaneous violations: some rulebooks use the arrow when both teams violate and no ordinary penalty gives one team the ball.
• Period starts in some competitions: after the opening jump, later periods may begin with an alternating-possession throw-in instead of another jump ball.

Important exceptions

• A foul can come first: holding, pushing, reaching across the body, or excessive contact can be a personal foul before the ball is legally tied up.
• Clear control prevents the call: a defender touching the ball does not create a held ball if the ball handler still has sole control and can play normally.
• League rules differ: the NBA, WNBA, FIBA, NCAA, NFHS, youth, and local competitions do not all use the same jump-ball and arrow mechanics.
• Administrative errors have limits: a wrong arrow may be correctable, but the timing and remedy depend on when the mistake is discovered.
• Special restart rules can override it: double fouls, suspended play, replay corrections, or end-of-period situations may have their own point-of-interruption or restart provisions.

Common arguments

• "Any two hands on the ball is a held ball" is too broad. Officials need firm simultaneous control or a rulebook-defined trapped-ball situation.
• "The stronger player earned possession" misses the purpose of the rule. Once a held ball exists, the restart is neutral and rule-driven.
• "The arrow is the same as last touch" is wrong. Last touch decides many out-of-bounds plays; the arrow is for neutral or unresolved possession situations.
• "The arrow changes on the whistle" is usually wrong. The arrow changes when the alternating-possession throw-in is completed or used as the rulebook defines it.
• "Every basketball game uses the arrow" is wrong. Some competitions use actual jump balls where other competitions use alternating possession.

What officials look for

Officials try to distinguish strong defense from a true tie-up. A clean hand on the ball may be legal defense, while grabbing arms, displacing the ball handler, or forcing a player through illegal contact can be a foul. If both opponents lock onto the ball and continued play would become a wrestling match, the held-ball whistle is the safer and more accurate ruling.

After the whistle, officials confirm the arrow or jump-ball procedure with the scorer's table, identify the correct restart location, and communicate the direction clearly. On arrow plays, the table must change the arrow only at the proper time so the next alternating-possession situation is not given to the wrong team.

Practical examples

• Clean trap: a defender gets both hands firmly on the ball while the ball handler also holds it. Neither player can gain control without roughness, so the official calls a held ball.
• Not a held ball: a defender knocks the ball loose for an instant, but the dribbler immediately recovers without shared control. Play continues unless another violation or foul occurs.
• Arrow throw-in: Team A has the arrow, receives the alternating-possession throw-in, and completes the throw-in legally. The arrow then points to Team B.
• Professional jump ball: in a competition that uses actual jump balls for held balls, the tied-up players or eligible substitutes jump instead of using an arrow throw-in.
