McCarthy (undisclosed) went to the blue medical tent during Sunday's game at Philadelphia, Jordan Raanan of ESPN.com reports.
McCarthy took a big hit to the midsection from Eagles linebacker Zack Baun in the third quarter and was in obvious discomfort as he went to the sideline. The nature of McCarthy's injury isn't known, but Jameis Winston will fill in for him for as long as he's out of the contest.
