Bogut was expected to start in the Bucks' exhibition game against the Memphis Grizzlies, but ran off the floor less than an hour before game time. Bucks officials said he got dressed and left the arena.
Bogut participated in pregame warmups and was working on using the right hand that was encased in a glove. He also was wearing a shooting sleeve on his right arm.
The Australian star dislocated his elbow, sprained his right wrist and broke his right hand April 3 against Phoenix when he fell after a dunk.
Ersan Ilyasov moved into the starting lineup at forward, and Drew Gooden shifted to center with Bogut out.
