The 2003 AL Cy Young Award winner has made two starts this season, beating Minnesota and then losing to Tampa Bay on Sunday. He had been expected to make his third start Saturday in Chicago against the White Sox but is now slated to work during a three-game series against Boston in Toronto beginning April 21.
"I don't think it is anything serious," manager John Gibbons
said. "He went back to Toronto with tenderness in his forearm. It
should just be one start."
The injury was revealed by general manager J.P. Ricciardi at the Red Sox's home opener against the Blue Jays on Tuesday.
Halladay (1-1) was 12-4 with a 2.41 ERA in 19 starts last season. The right-hander was leading the AL in ERA when his left leg was broken by a line drive on July 8. He missed the rest of the season.
Burnett, sidelined since scar tissue broke away in his surgically repaired right elbow during spring training, made his second rehabilitation start Tuesday at the Blue Jays' facility in Dunedin, Fla. He threw 58 pitches in four innings and allowed two earned runs, six hits and no walks with four strikeouts.
"A.J. is coming back a day early" because of the injury to
Halladay, Gibbons said, "so we cut down his pitches today."
