Offseason injury news
"We're in a lot of trouble if he can't play," Kampe said.
Surgeons removed a quarter-sized piece of cartilage in a procedure Kampe called "fairly complicated."
Kampe said he is planning at this point to have Valentine available when the season rolls around.
If that wasn't big enough injury news, point guard Reggie Hamilton had a growth removed from his chest this week. Hamilton's family has a history of breast cancer, Kampe said. Hamilton also has a lingering hip problem and Kampe is hoping the rest between now and the beginning will help rest his gunslinging PG.
"I'm probably the only one who is healthy," joked Kampe, who had double knee replacement surgery in May.
Practice begins in October and the Grizzlies open the season vs. Spring Arbor at the O'rena Nov. 3.
