NBA players foul out after 6 personal fouls in a regulation game. Players are also ejected after 2 technical fouls or 2 flagrant-1 fouls. In college basketball (NCAA) and high school, the limit is 5 personal fouls.
Read the foul count separately from the ejection rules: personal fouls, technical fouls and flagrant fouls do not all trigger the same outcome. The sections below explain those distinctions and how foul trouble affects substitutions.
How Many Fouls Until You Foul Out in the NBA?
The NBA allows each player 6 personal fouls per game. When a player commits their sixth foul, they are disqualified from the rest of the game and must leave the floor. The team does not lose a roster spot; a substitute checks in for the disqualified player.
Personal fouls include common defensive fouls, offensive fouls, and loose-ball fouls. Technical fouls count toward the team total in some situations but have their own separate ejection rule.
Other Ways Players Get Ejected
Beyond 6 personal fouls, a player is automatically ejected after 2 technical fouls in one game, or 2 flagrant-1 fouls. A single flagrant-2 foul is an immediate ejection. These ejections can also carry fines and suspensions depending on severity.
NBA vs College vs FIBA Foul Limits
The NBA and WNBA use a 6-foul limit over 48 and 40 minutes respectively. NCAA college basketball and US high school basketball disqualify players at 5 personal fouls. FIBA international games, including the Olympics, also use a 5-foul limit over 40 minutes. The NBA’s extra foul reflects its longer game.
What Happens When a Player Is in “Foul Trouble”?
Coaches often bench a starter who picks up 2 fouls in the first quarter or 3 by halftime to protect them from fouling out in the fourth quarter. This is why star players sometimes sit long stretches even in close games.
