According to Racine Journal Times columinst Gery Woelfel, Sanders is being investigated because he got into a bar fight last weekend.
Milwaukee television station TMJ4 is reporting that police want to talk to Sanders about a fight that happened at a Milwaukee club where Sanders allegedly threw punches and broke champagne bottles over the heads of people while security personnel tried to break up a fight in the club's VIP section.
Sanders did not practice yesterday because of a swollen right thumb.
Sanders, 24, is averaging just three points and four rebounds per game through the team's first three games this season. The team gave him a $44 million extension over the offseason.
The Bucks released a statement Wednesday night:
"We are aware of an incident from Saturday evening. The matter is under investigation and Larry Sanders is cooperating fully. At this time we will have no further comment.”
