Dixon, the brother of former Maryland guard Juan Dixon, broke his foot when he stepped on someone else's foot during a pickup game. He had surgery to repair the injury Wednesday and is expected to return to the Panthers sometime in late November, possibly for the CBE Classic in Kansas City against Wichita State.
Dixon broke the same foot earlier this summer, also while playing basketball, and underwent surgery.
Dixon is Pitt's lone returning starter from last season's Elite Eight team. He averaged 8.4 points and 2.6 rebounds last season.
The Panthers are expected to start Ashton Gibbs at the point in place of the departed Levance Fields. Gibbs led the U.S. Under 19 team, which was coached by Pitt's Jamie Dixon, to a gold medal in New Zealand this summer.
