Dr. Timothy Kremchek -- an arm specialist based out of Cincinnati -- examined the results of an MRI taken on McGowan's ailing right shoulder and confirmed that there was no new damage in the pitcher's throwing arm. McGowan is scheduled to meet with Kremchek later this week to be further evaluated.
McGowan exited a start last Tuesday after throwing 66 pitches in just four innings due to pain in his shoulder. Initial tests performed by Toronto's medical staff showed that there was a slight tear in McGowan's right rotator cuff -- a similar problem the pitcher dealt with last season.
When the Jays compared McGowan's latest MRI results to a similar exam performed a year ago, the team determined that there was no further damage to the arm. Kremchek agreed with that assessment, meaning McGowan is likely suffering from inflammation in the shoulder.
Toronto originally indicated that the 26-year-old McGowan would need to miss at least a month before rejoining the rotation, though there's no set timetable established. In 19 starts for the Blue Jays this season, McGowan is 6-7 with a 4.37 ERA and 85 strikeouts across 111 1/3 innings.
