Stephen Drew (concussion) will likely visit a concussion specialist in Pittsburgh. The Red Sox won't make a final decision on the next step until Tuesday, but Drew continues to have symptoms related to when he was hit in the helmet by a pitch on March 7. Barring a rapid recovery, he figures to open the season on the disabled list. Jose Iglesias would likely handle starting shortstop duties in that case, though Pedro Ciriaco could also factor in.
