Mo Williams out vs. Grizzles, J.R. Smith possibly out as well

When the Cleveland Cavaliers tip-off in Columbus later today, they will certainly be without one key player and will possibly be without another.

According to reports media members in Columbus, guard Mo Williams will sit tonight so he can rest and guard J.R. Smith may miss tonight's game with a hamstring issue. Smith's status will be decided based on how shootaround goes.

Mo Williams will sit out the Cavs game tonight for rest. J.R. Smith (hamstring) could sit, depending on how he comes through shootaround.

#Cavs will not have Mo Williams in lineup tonight versus Grizzlies. J.R. Smith will possibly sit tonight, too. He's battling hamstring pain.

Williams and Smith have been the Cavs' typical starters in preseason so far and it isn't clear who would start in their place. One option would be to start Matthew Dellavedova at point guard and Joe Harris at shooting guard.

Williams is averaging 5.5 points per game in the preseason, while Smith is averaging 15 points per game.
