Cavaliers forward Jeff Green underwent an MRI on his sore lower back Saturday that revealed no structural damage, according to coach Tyronn Lue. Green will be held out of the Cavs' lineup as Cleveland finishes its five-game home stand Saturday against the Denver Nuggets and Monday against the Detroit Pistons to give his back a chance to rest. "We know he's going to be out at least the next two games and then we'll kind of re-evaluate from there," Lue said. Green missed the Cavs' 129-123 win over the Brooklyn Nets on Tuesday with the same back issue. In four games played since the All-Star break, Green is averaging 7.5 points on 40.7 percent shooting (20 percent from 3) and 2.5 rebounds. Prior to the break, he was averaging 10.7 points on 48.9 percent shooting (32 percent from 3) and 3.4 rebounds.
