Gentry is now dealing with sinus issues in addition to his lingering concussion symptoms, Jane Lee of MLB.com reports. It's been a week now since Gentry suffered a concussion in a collision with White Sox second baseman Carlos Sanchez, and it sounds like he's yet to completely shake the cobwebs. There is no set timetable for Gentry's return to action, but manager Bob Melvin did confirm that he will not be available off the bench Tuesday.
