Lackey (bicep) injured his right arm on the 76th pitch of his debut against the Toronto Blue Jays on Saturday, his first regular season start since undergoing Tommy John surgery on his throwing arm last year.
The Red Sox recalled right-handed pitcher Alex Wilson from AAA Pawtucket to replace him on the active roster. Wilson has given up three runs on four hits in the 2 2/3 innings he has worked so far this year.
ESPNBoston.com’s Gordon Edes is also reporting that Alfredo Aceves will replace Lackey in the starting rotation.
