That should put him out until the end of preseason, but Tyronn Lue says that he could heal faster than expected, via Cleveland.com:
"We'll see how he feels," Cavs coach Tyronn Lue said. "He always heals pretty good. He heals faster than anyone I've ever seen. We'll just see how he feels."
Lue also said that he didn’t expect rookie Cedi Osman, who’s been dealing with back spasms, to play against the Pacers on Friday. Lue did say that he liked what he saw from Osman after being pressed into more minutes in the wake of Shumpert’s injury, via Cleveland.com:
"He played a little bit more minutes than we expected," Lue said of Osman, the 22-year-old rookie who came over from Turkey. "I think tomorrow he'll probably be out and then be ready to go on Sunday."
Lue also said of Osman: "I liked him a lot (against the Hawks). We've been talking a lot about him throughout the course of this preseason. Just practices, knows how to play, can defend, can make the plays. He's a smart player. I really like him a lot."
Osman will certainly have more chances to make impressions in the short term while Shumpert recovers. We’ll see how long Shumpert will be sidelined. For now, expect him out the rest of the preseason and consider any earlier return as a pleasant surprise.
