The Toronto Blue Jays might have lost one of their expensive new pitchers before the season even starts.

A.J. Burnett hurt his pitching arm Saturday and left Toronto's 8-4 loss to the Boston Red Sox after throwing one pitch in the second inning.

The right-hander signed a $55 million, five-year contract with the Blue Jays during the offseason after going 12-12 with a 3.44 ERA for the Florida Marlins in 2005.

Blue Jays manager John Gibbons motioned to the area above and below the inside of his right elbow when describing where Burnett's problem was.

"He went to get an MRI and check it out. It could be his forearm, and it could be his elbow. We don't know," Gibbons said. "He has had that elbow reconstructed in the past, so he knows his body."

The Blue Jays have a Carl Pavano of their own??
