Kyrie Irving's up-and-down second season might be mostly finished.
Irving's injury won't require surgery, but he'll sit just to rest it.
The injury happened late in the third quarter when Irving attempted a baseline drive but was bumped hard out of bounds. Irving's left shoulder hit Jonas Valanciunas hard in the midsection. Irving remained on the ground in serious pain before staying in to shoot his free throws -- one-handed -- and then leaving the game.
The Cavs have 19 games left, and if Irving misses the full four weeks, he would return only to play in Cleveland's final three games.
Irving, 20, is averaging 23.0 points and 5.7 assists in 49 games this season.
