FIBA says the new edition of its Official Basketball Rules took effect worldwide on October 1, 2026, per FIBA. The changes below come from FIBA's own summary of rule changes (version 1.0a, published June 2026), which says the final rulebook prevails if the two differ. They matter to an American on a first overseas deal because the foul that, in pairs, used to end a night, the unsportsmanlike foul, no longer exists.

What replaced the unsportsmanlike foul?

Two new fouls. A disruptive foul is illegal contact that does not reach the level of a flagrant foul but disrupts the flow of the game and puts the opponent at a disadvantage, per FIBA's summary. The listed cases are unnecessary contact to stop an offensive team's progress in transition before the shooter begins the act of shooting, unnecessary contact to stop the game or shot clock at the end of a quarter or overtime, and contact from behind or from the side on an opponent who is progressing to the basket with no defender between the player and the basket, while that player has, is going for or is receiving the ball and before the act of shooting starts.

A flagrant foul is contact that violates the spirit of sportsmanship, such as an act that is not a legitimate basketball play, is reckless, violent or dangerous, or involves excessive, hard contact. Both carry free throws and a throw-in, and a flagrant foul adds a jump ball at the start of the first quarter, per FIBA.

What counts toward a game disqualification now?

FIBA's stated reason is that the old rule, which disqualified a player after any two technical or unsportsmanlike fouls, was "overly strict." Under the new text a player is disqualified after:

• two category 1 technical fouls,
• two flagrant fouls, or
• one category 1 technical foul and one flagrant foul.

Disruptive fouls and category 2 technical fouls do not count, per FIBA. Category 1 technicals cover behavior such as disrespecting officials, taunting, faking a foul and waving a hand near an opponent's eyes. Category 2 covers delay of game, hanging on the ring and a defensive goaltend on the last free throw. A head coach is disqualified after two category 1 technicals for personal conduct, or three category 1 technicals tied to the bench.

What changes on shooting fouls?

The definition of the act of shooting is rewritten. On jump shots and other moving shots, it starts when the player begins to move the shoulders and the ball upward toward the basket. On drives, it starts when the player has gathered the ball and continues the shooting motion. A player must be in the frontcourt to be in the act of shooting, with an exception for the last action before a quarter or shot clock expires. On jump shots, a player who is fouled and then passes the ball off, or is not facing the basket as the ball moves up, is no longer treated as shooting; on drives, passing the ball off ends it, per FIBA.

A BasketNews commentary argues the wording has a practical effect: a player fouled before the shoulders move upward may not get a shooting foul, per BasketNews. Those are one writer's concerns, not FIBA's position.

What does instant replay cover now?

Two additions, per FIBA. At any point in a game, officials may review a goaltending or interference violation after a foul is committed. In the last two minutes of the fourth quarter and each overtime, they may review whether the thrower-in still held the ball when a defensive team committed a foul on a throw-in. The summary says both also apply to the head coach's challenge, which can be requested at any time.

Which leagues use these rules?

FIBA's announcement does not say which leagues adopt the text, so a player should check the competition rules of the league that signs him or her. The EuroLeague published its own 2026-27 changes in September: technical fouls split into two categories, the unsportsmanlike foul replaced by disruptive and flagrant fouls, and a similar act-of-shooting definition, per BasketNews. That report presents them as EuroLeague's changes and does not state that they match FIBA's text word for word.

What should an American signing overseas do?

Read the rulebook of the league, not only the FIBA summary, and ask the club to confirm which one governs. A player moving to a club in another country also needs the letter of clearance before playing. The contract terms around discipline and fines, which the overseas contracts guide covers, matter more now that a disqualification follows only from category 1 technicals and flagrant fouls, not from disruptive or category 2 fouls. The body behind the rulebook is explained in what FIBA stands for.
