Doc Rivers confirmed the Boston Celtics’ interest in adding players to their injury-depleted roster.

The Celtics are looking to fill the void left by the loss of Rajon Rondo, Jared Sullinger and Leandro Barbosa.

"Danny [Ainge] and I, we thought about it and we all have been thinking about it since all the injuries," Rivers said. "With the last one with Barbosa, now we can't look at one position anymore. That's what we were looking at — looking at size first, then a guard. Now we're looking at players. We need players. We need to pick up a couple of players as soon as we can get them. That's what basically we're doing.

"But we don't want to do anything so quick that somebody else comes available and then we don't have room because we're at the cap threshold. We have to be very careful in what we do."

Asked what kind of player would help most right away, Rivers said: "I would say a ball-handling guard. It's no longer a point guard, it's just a guard. If I had my perfect guard for this group right now, it would be a guard that can play multiple positions and that can shoot, that has some toughness.

"And then you need a big. You're not going to find a center, so a four. Obviously a five would be great, but a four that can stretch the floor. Or a four that can rebound, just a great rebounding four that has skills.”
