Ray Allen could return from injury on Wednesday and his new role could be coming off the bench.

The Celtics have found success in pairing Rajon Rondo with Avery Bradley.

“We think about stuff like that all the time, no doubt,’’ Rivers said after Tuesday’s practice. “That, and other guys. We’ll see how it goes. Maybe it will be somebody else, we’ll see.’’

Allen said he would accept a bench role.

“Whatever we need to do as a team,’’ Allen said. “I think the effort that I’ve seen over the last week and a half, two weeks, is great. Whatever combinations we work out there, we’re all good enough, we’re all professional enough, to understand it. We know our plays. We’re at a point in the season where everybody knows who each other is. So, remembering plays and positions is second nature now for all of us.’’
