Perkins' shoulder not ready for contact drills in camp

NEWPORT, R.I. -- Boston Celtics center Kendrick Perkins will be kept out of scrimmages during training camp because of offseason surgery on his left shoulder.

Celtics coach Doc Rivers said Tuesday that Perkins is allowed to run the floor "as long as no one else is running up and down the floor with him."

Perkins injured his shoulder in Game 4 of the NBA Finals against the Los Angeles Lakers. He missed Games 5 and 6 as the Celtics won their record 17th championship.

Doctors told Perkins he could probably return for the third preseason game, but Rivers said he might hold him out the first four exhibitions in the hopes of getting him ready for the Oct. 28 opener.
