High Quality Content by WIKIPEDIA articles! In basketball, a technical foul (also informally known as a "T" or a "Tech") is any infraction of the rules penalized as a foul which does not involve physical contact during the course of play between players on the court, or is a foul by a non-player. The most common technical foul is for unsportsmanlike conduct. Technical fouls can be assessed against players, bench personnel, or even the entire team. They (along with their penalties) are more serious than a personal foul, but not as serious as a flagrant foul.
