BALTIMORE – Brian Roberts will undergo surgery on his right hamstring on Thursday in Dallas.
Roberts, who suffered an injury to the hamstring at Tampa Bay on Apr. 4, will undergo a semitendinosus release. The semitendinosus is a muscle in the back of the thigh.
He’s expected to be out six weeks and will report back to Sarasota, Fla. for rehab.
The surgery will be performed by Dr. Daniel Cooper in Dallas.
Roberts has been rehabbing in Sarasota and originally though he could return within a few weeks, but he hasn’t been making the progress he thought he should and consulted with Dr. Cooper.
“He just didn’t like the way he felt,” manager Buck Showalter said on Tuesday. “He was a little frustrated it hadn’t come faster.”
Roberts has been limited to 118 games the past four seasons with two concussions, a back injury, hip surgery and now surgery on his hamstring.
