Brandon Webb will not undergo rotator cuff surgery on Aug. 1 as previously reported. Instead, he will have arthroscopic surgery on the ailing right shoulder. His agent, Jonathan Maurer, said no "major" work would be done on the shoulder.

There had been reports -- and they had been confirmed by Webb's agent -- that the former Cy Young winner would undergo rotator cuff surgery, but further tests on Friday determined he will not undergo the surgery to have the delaminated part of the rotator cuff reattached. It's still doubtful Webb will pitch again this season, but his career is not over, Maurer said.

"He will be back for sure," Maurer wrote in a text earlier on Friday.

Webb signed a one-year deal worth $3 million with the Rangers in December with bonuses for innings pitched and days on the roster that could reach another $5 million. He obviously hit none of those, making just four starts for Double-A Frisco. He went 0-2 with a 9.75 ERA, allowing 21 hits and 13 runs in 12 innings. He struck out eight and walked six.

Webb hasn't pitched in the majors since opening day of 2009 for the Diamondbacks. He had shoulder debridement surgery in August of 2009 and tried to come back for Arizona at the end of last season.
