Twins outfielder Ben Revere, righthander Nick Blackburn and first baseman Justin Morneau all underwent surgeries on Friday.
According to Twins general manager Bill Smith, Revere had his left knee cleaned out and had a couple of loose pieces of cartilage removed. Revere was seen in the clubhouse with ice on his knee in recent weeks.
Blackburn was diagnosed with Radial Tunnel Syndrome and had surgery to remove pressure on a nerve in his forearm. He will need six to eight weeks to recover.
Morneau underwent a stabilization procedure on a tendon in the back of his left wrist. Smith, in an e-mail, wrote that Morneau will be in a cast for six weeks.
Morneau had neck surgery in June to remove a herniated disk fragment. He was dealing with numbness and weakness in his left hand and wrist, but said earlier this week that he still had numbness in a couple fingers in his left hand. Smith wrote that the surgeries were part of end-of-season physicals.
