Tillman (knee) said Friday that he doesn't have a timetable to return, John Karalis of BostonSportsJournal.com reports.

EDGE Analysis

Tillman was traded from the Grizzlies to the Celtics on Wednesday, but he's been dealing with a left knee injury recently. He participated in Boston's morning shootaround ahead of Friday's game against the Wizards, but his comments afterward imply that he'll be sidelined against Washington. Once Tillman is healthy, he will fight for reserve center minutes with Al Horford and Luke Kornet.
