BOSTON -- Pitcher Aaron Cook, who is on the disabled list after suffering a gash below his left knee during his only start for the Red Sox, has experienced something of a setback.
Cook had the stitches removed from the knee nine days ago in Philadelphia and then threw a bullpen session, the first step to going on a rehab assignment.
But the wound reopened while the Sox were in Baltimore, stalling his comeback.
"He's now doing the leg work that he needs to do to keep his arm in shape,'' said Bobby Valentine. "I think he's just about ready to start the bullpen sessions (again) full bore.''
Cook will probably throw a couple of side sessions before the Sox assign him to a minor league affiliate to begin his rehab time.
"I don't know if he'll be a starter or reliever (when he's healthy again),'' said Valentine. "We'll try to build up his arm strength and get him pitching again in rehab games.''
