Red Sox manager John Farrell said Pedroia will return to Boston to be examined by a doctor Monday morning. The star second baseman got hurt when he was taken out on a potential double play last weekend against Milwaukee.
Pedroia remained in the lineup all week but Farrell said the soreness ''continues to persist and probably gain in intensity.'' The 2008 AL MVP is batting .236 with no homers and one RBI in 55 at-bats. He has three extra-base hits and hasn't drawn a walk all season.
''I think there's probably a direct correlation to what we've seen at the plate,'' Farrell said.
In other injury news, closer Koji Uehara (stiff shoulder) remained unavailable, though he went through his normal pregame throwing routine on flat ground.
''He came away from it encouraged,'' Farrell said. ''He felt better than he actually expected.''
Uehara still will be examined by the team's medical staff in Boston on Monday, when the Red Sox are off. He is expected to join the club Tuesday in Chicago for a three-game series against the White Sox.
''We'd still like to get him off a mound in a bullpen session before getting back in a game, but today overall was very good news regarding Koji,'' Farrell said. ''He was really able to generate good arm speed, and he's moving past some of the concerns mentally that he had.''
Red Sox outfielder Shane Victorino (strained right hamstring) ran the bases again and also was headed to Boston for a checkup Monday. If that turns out OK, he's on track to begin a rehab assignment Tuesday with Double-A Portland, Farrell said.
