Ray Allen, Keyon Dooling Must Step Up in Avery Bradley’s Absence (Video)

When one man is out, the others step up. That's the Celtics way.

Avery Bradley will miss Monday's Game 5 against the Philadelphia 76ers with lingering shoulder issues, which Celtics head coach Doc Rivers said before the game have now spread to his right shoulder as well.

"I don't know when," Rivers said when asked about when Bradley can be expected to return, noting offseason surgery could erase some of the problems that have flared up with his recent injuries. "The strength just won't return."

With Bradley out, Ray Allen will be called on to fill his role, both in the starting lineup and on defense. Allen is a more than capable replacement, but the reason he's the replacement at all is because he's been dealing with ankle injuries himself.

Veteran guard Keyon Dooling and Marquis Daniels will also put in more time with Bradley out, Rivers said.

"Keyon will take on a bigger role, obviously, and so will Ray, obviously," Rivers said. "… But Ray is limited with his health."

Rivers also talked about the contributions that Ryan Hollins and other young players have made for the Celtics so far this postseason, and what's needed from them for Boston to continue to find success.
