Shumpert leaves game after appearing to injure ankle on flubbed fast-break dunk

Iman Shumpert has been a terrific addition to the Cleveland Cavaliers' bench since they acquired him in a January trade. 

But Shumpert's specialty is defense, and his comparative lack of polish at the offensive end was on display against the Philadelphia 76ers on Sunday. 

On top of blowing the wide-open dunk attempt, Shumpert appeared to come down a bit awkwardly. 

He ended up going to the locker room just before halftime and did not return to the game due to an unspecified left ankle injury.
