ARLINGTON -- The Rangers revealed that pitcher Derek Holland underwent microfracture surgery on his left knee last Friday during an operation to repair torn cartilage behind the kneecap.

Microfracture surgery, designed to stimulate the blood flow behind the kneecap, is more serious than a regular operation for torn cartilage, and it is why Holland could be out until the All-Star break. Holland injured the knee falling on the stairs at his house while playing with his dog, and he will be on crutches for six weeks until he can begin a full rehabilitation program.

Holland was expected to be in a rotation that includes Yu Darvish, Matt Harrison, Martin Perez and Alexi Ogando. Nick Tepesch, who began last season as the Rangers' fifth starter, is the leading candidate to replace Holland. The Rangers also re-signed pitcher Colby Lewis to a Minor League contract and will also consider moving either left-hander Robbie Ross or right-hander Tanner Scheppers out of the bullpen.
