If Varejao is out for a significant period, it's believed that the Cavs will intensify their months-long efforts to trade for a big man. The team has been seeking additional help for their front line going back to the summer, having specifically targeted Timofey Mozgov of the Denver Nuggets and Kosta Koufos of the Memphis Grizzlies.
Sources say that the Cavs, in recent days, have been in contact with the Boston Celtics about working as a facilitator in three-team trade scenarios. The Celtics, blessed with frontcourt depth in the wake of their recent acquisition of Brandan Wright in the Rajon Rondo deal, have been aggressive recently in their attempts to acquire future draft picks.

I think Boston wants Waiters and/or a pick or a scoring guard from a third team.
