McGowan, who hasn't pitched a full season since 2007, suffered yet another setback during the first week of Spring Training, when he experienced some soreness in his right shoulder while throwing off flat ground.
"He came up a little lame and his shoulder was barking a little bit," said Blue Jays manager John Gibbons. "So he's kind of on the back-burner again. He's going to do everything, but he's not going to be on the mound -- another little setback."
McGowan appeared to turn a corner during the 2011 season, when he made his first appearance in the big leagues since '08. The following spring, he entered camp as the favorite to win the club's No. 5 spot in the rotation, but a foot injury dashed any hopes of heading north.
The foot injury was eventually replaced by a shoulder injury and he was unable to throw a single inning in either the Majors or Minors. There wasn't much information available on his status until Wednesday, when Gibbons revealed the hard-throwing righty was still experiencing pain.
McGowan, who owns a career 20-24 record with a 4.80 ERA over five seasons, has since been essentially shut down. Gibbons was relatively vague in his details and said while McGowan will still be able to work out, he is unable to go through a normal throwing program. There is no timetable for his return to the mound.
"He's had a tough road," Gibbons admitted. "You would love to see him bounce back and have a nice, solid, long, productive career. Right now, we really don't need him the way we're set up [in the rotation], but as the season goes on, you never know. He's got plenty of time."
