SURPRISE, Ariz. -- Rangers pitcher Andrew Cashner received a pain-relieving injection into his right shoulder after being examined in Dallas on Friday.

Cashner is expected to return to Arizona and begin a light throwing program on Saturday. He was shut down because of soreness in his right biceps tendon and the Rangers don't expect him ready for the start of the season.

But the Rangers are hopeful that it is not a serious issue. Normally a starting pitcher takes 6-8 weeks of a throwing program to get ready for the regular season, but it may not take that long with Cashner because he has been throwing for three months before being shut down.

"There is already some equity in his throwing program," manager Jeff Banister said.

Cashner and Tyson Ross were signed this offseason to fill the back end of the Rangers rotation. Ross is recovering from thoracic outlet syndrome and is also in the early stages of a throwing program. He is expected to throw off a mound for the third time on Saturday.
