Red Sox shortstop Stephen Drew was diagnosed with a concussion 10 days ago after getting beaned in the batting helmet by a pitch. And the 30-year-old has not made a whole lot of tangible progress since.

Scott Lauber — Red Sox beat writer for the Boston Herald — reports that Drew “has been cleared only to lightly play catch, not to take batting practice or ramp up his physical activity.” Which prompted Red Sox manager John Farrell to acknowledge Sunday morning in Fort Myers, Florida that “the window is narrowing” on Drew’s chances of opening the regular season as a member of the active 25-man roster.
