Creighton point guard Austin Chatman will have surgery to repair a ligament in his right thumb and is expected to be fully recovered before the season.
The school said Tuesday that Chatman would wear a cast for two months.
Chatman is the only returning starter for a team that has made the NCAA tournament three straight years. Chatman has started 71 straight games and averaged 8.1 points as a junior. He's the Bluejays' top returning scorer.
Chatman scored 10 or more points in six of the last seven games and was named to the Big East all-tournament team.
