Morris suffered a season-ending knee injury in Sunday's 20-10 loss to the Texans, Adam Schefter of ESPN reports.
Morris drew the start at left tackle in Week 14, but he was forced to exit the game after just one play due to a knee injury. Esa Pole replaced him in the contest, and if Jawaan Taylor (elbow) remains sidelined moving forward, Pole could remain in the starting lineup.
