Morris hurt his shoulder in Saturday's preseason game against Pittsburgh and has been ruled out from returning.
Morris caught two of four targets for 20 yards prior to going down with the injury. While he's well behind Dalton Kincaid and Dawson Knox in Buffalo's tight-end pecking order, Morris is a strong favorite to make the squad as the team's third tight end if he is healthy. Morris has seen more work on special teams than on offense during his first two NFL campaigns.
