SEATTLE -- A MRI exam on right-hander Carlos Silva's right shoulder on Monday showed an internal impingement and fraying of the labrum and rotator cuff.
A Mariners official said results of the exam would be sent to David Altcheck, an orthopedist, for a second opinion. A further update will be forthcoming later this week.
Silva, who is in the second year of a four-year, $48 million contract, was placed on the 15-day disabled list on May 9 with a sore shoulder. He has a 1-3 record and 8.48 ERA in six starts.
Silva started the 2008 season with three consecutive wins, but then lost 15 of his final 16 decisions.
