HOUSTON -- The back end of the Rangers' rotation is going through considerable turmoil right now. One thing that's becoming clear is Rich Harden and Derek Holland, both on the disabled list, will not be back anytime soon.
Harden, on the DL with a strained gluteus muscle, was supposed to resume light throwing on Thursday, but that was delayed. Instead, Harden received an injection on Friday to relieve the pain and inflammation and will not resume throwing until early next week.
Harden was placed on the DL on Sunday after going 3-3 with a 5.68 ERA in 13 starts. Even after he resumes throwing, Harden will likely need at least two rehab starts, and it's unlikely he'll be back before the All-Star break.
The Rangers were hoping Holland would be back in time for a three-game series against the Angels from June 29-July 1. But that hope may have taken a hit on Friday.
Holland, who has been throwing in Arizona, re-injured his right knee during fielding practice at the Rangers' complex in Surprise, Ariz. This is a similar injury to what he suffered at the beginning of Spring Training when he was sidelined for a couple weeks with a sprained knee.
Holland, who was supposed to have a significant throwing session on Saturday, has been temporarily shut down. He will be examined on Saturday in Arizona by Keith Meister, who is the Rangers' team physician.
The Rangers could have another starting option emerge in the next few weeks. Brandon McCarthy is expected to come off the disabled list at Triple-A Oklahoma City on Saturday.
