‘Doyle, who is returning from an ACL tear in his right knee sustained last September, went down in the third quarter of Buffalo’s 27-15 loss. Trainers put Doyle’s leg into an air cast and he was able to stand briefly before sitting onto the cart. Teammates, including offensive linemen Mitch Morse and Spencer Brown, surrounded Doyle before he was carted to the locker room. The Bills ruled out his return soon after.’
