The move is retroactive to Tuesday and followed a bullpen session by Buchholz before Wednesday nights game against the Atlanta Braves. "We had a chance to sit down and talk to him before he went out on the field," manager John Farrell said before knowing the results of the session, "but were going to be cautious. We dont want to put him at risk of suffering any other type of injury, whether thats to the knee or shows up elsewhere. Weve got to be careful." The Red Sox recalled right-hander Alex Wilson from Triple-A Pawtucket to fill Buchholzs roster spot. On Monday, Buchholz walked a career-high eight while allowing six runs in three-plus innings of an 8-6 win at Atlanta that ended Bostons 10-game losing streak.

Buchholz is 2-4 with a 7.02 ERA in 10 starts. Last year he was 12-1 with a 1.74 ERA in 16 starts and made the AL All-Star team for the first time. In four post-season starts, he was 0-0 with a 4.35 ERA as Boston won the World Series. He had missed three months with a neck injury before coming off the disabled list on Sept. 10. Wilson pitched one inning in relief in two previous stints with Boston this season. At Pawtucket, he was 1-0 with five saves and a 1.42 ERA in 18 relief appearances. He made his major league debut last year, going 1-1 with a 4.88 ERA with Boston.
