BOSTON -- Boston Red Sox outfielder Jacoby Ellsbury, who suffered a subluxation of his right (non-throwing shoulder) last Friday, had his MRI exams read by noted California orthopedist Dr. Lewis Yocum and will not need immediate surgery, manager Bobby Valentine said Tuesday.

"There was a consensus of opinion on both the damage and how to proceed," Valentine said of the consultation with Yocum.

"He had some hand manipulation for range of motion. They're trying to take it slowly to get it better. I don't know that there is anything on the horizon other than the normal treatment and see how he does day by day," Valentine said.

Reports have suggested that Ellsbury, who has been receiving treatment since suffering the injury, might be out anywhere from four to eight weeks. But Valentine did not put a timetable on Ellsbury's return.

Another injured Red Sox outfielder, Carl Crawford, participated in his first extended spring game on Tuesday.

Crawford, who had surgery on his left wrist in the offseason and suffered a strained left elbow a couple of weeks ago, had four at-bats, according to Valentine. The manager said Crawford walked once and attempted a stolen base, and got the bat on the ball in his other three at-bats.

"He felt good after the game," Valentine said.
