Murphy likely done for season

Outfielder dealing with sprained right knee and bone bruise

ARLINGTON -- It's not official, but the writing seems to be on the wall for David Murphy.

Out since Aug. 6 with a sprained right knee as well as a bone bruise in the knee, Murphy isn't likely to play again this season.

"He probably won't play any more this year," manager Ron Washington said.

Washington hasn't told this to Murphy yet, but he doesn't really need to.

"It's doubtful," Murphy said about the status of his return this season. "I got a cortisone shot last Tuesday. I feel better. The swelling has gone down a good bit. But there's no point to prepare to try to play in Anaheim to end the season. I tried to hang on as long as possible, but it looks like the best thing to do is to shut it down."

Early estimates had Murphy out four to six weeks, but nearing the six-week anniversary of his home-plate collision with Ivan Rodriguez, Murphy is still experiencing some discomfort in the knee.

"That hasn't been the reality," he said. "At this point, I'm kind of past the frustration. It's just disappointing."

He said that the back and outside of the knee is where the swelling is still occurring and that the bone bruise is causing more of that than the ligament.

But, on the positive side, an MRI performed last Tuesday showed the same results as the first MRI, so he should be able to continue rehabbing the knee until he can begin his offseason program.

He said the doctors told him that strengthening his right quad would actually make the knee more stable going into next season.

"It feels great," he said. "If you saw me on an everyday basis walking, you wouldn't know anything was wrong. It's just running on it that's too much."
