Maresh's tumor not cancerous

Minnesota linebacker recruit Sam Maresh received some good news during the weekend, as tests revealed that the tumor in his left calf is not cancerous.

According to a message posted by Maresh's father Bill on the family's CaringBridge.org Web site, Maresh underwent a biopsy Friday at the Mayo Clinic in Rochester, Minn. The test showed that the tumor is only scar tissue.

"They said it was a dense tissue of no significance," Bill Maresh's message reads. "I called Sam as soon as I hung up and he was very happy. We will be talking with the doctors to discuss how they will remove it."

Doctors discovered the tumor several days earlier after Maresh experienced pain in his leg. He's expected to have surgery soon.

Bill Maresh told the Star Tribune that Sam likely will miss spring practice but should be back on the football field approximately six weeks after the surgery.

One of the top recruits in Minnesota's heralded 2008 class, Maresh was preparing to join the team last summer when doctors discovered a heart murmur. He underwent surgery June 26 to repair his aortic valve.

Maresh sat out last season but made a remarkably quick recovery and was on schedule to return to the field for spring ball until doctors discovered the tumor.
