Coach Bruce Arians said Monday that he's not sure whether Gronkowski (back) will be available for Sunday's game against Washington, Scott Smith of the Buccaneers' official site reports.

EDGE Analysis

Gronkowski is coming off a bye, but it looks like he's still troubled enough by back spasms to make his availability unclear. At least a bit more clarity regarding the veteran tight end's status should be available by the time Wednesday's first official injury report of the week is posted. If Gronkowski is unable to suit up at Washington, O.J. Howard and Cameron Brate will operate as Tampa Bay's top tight ends.
