Jameis Winston's left knee bent in a bad way as he was dragged down by the back of his jersey, and he ended up leaving Sunday's game on a cart.
Winston left Sunday's game against the Tampa Bay Buccaneers after a tackle by Bucs linebacker Devin White. White was called for a horse-collar tackle, though he didn't grab Winston by the collar.
Trevor Siemian, the former starter with the Denver Broncos, took over. Taysom Hill, Winston's main backup, is still out due to a concussion suffered three weeks ago.
