John Lackey made a successful rehab start for Double-A Portland Tuesday night and is in line to return to the Red Sox' rotation on Sunday against Houston.

Manager John Farrell says John Lackey 's range-of-motion issues from his biceps injury are gone, and the right-hander will begin a throwing program on Tuesday.

John Lackey felt some tightness in his biceps during a throwing session on Tuesday, so the Red Sox made the decision to shut him down.

Alex Wilson was called up from Pawtucket to replace the injured John Lackey . He will come out of the bullpen in Aceves' spot, who is replacing Lackey in the rotation.

John Lackey is placed on the 15-day disabled list (retroactive to April 7) because of the right biceps strain, and is replaced by PawSox reliver Alex Wilson.

The 'prognosis is good' for John Lackey after a second opinion, according to WEEI.com.

The Red Sox are still in a "wait-and-see" mode when it comes to John Lackey , who left his first start in almost 18 months in the middle of an at-bat Saturday with a strained biceps.

John Lackey , who came out of Saturday's start in the fourth inning after suffering a strained right biceps, is in Boston awaiting an examination by team othropedist Dr. Peter Asnis and a follow-up MRI.
