Rajon Rondo has ruled himself out for Game 5.

Rondo had been ramping up his activity in hopes of returning from his broken thumb early.

"I think I'm Wolverine," Rondo said at a shootaround Wednesday. "But it actually hasn't healed that quickly yet."

Rondo still hopes he could play in Game 6.

"My thumb is still the same," he explained. "Still broke."

Rondo could do further damage to the thumb if he plays.

"If I didn't go out there with anything, the slightest fall on the floor might further damage it," Rondo said. "If I was to go out there in Game 7, 8 or 9, I'd probably have a wrap."
