Morris will start at left tackle against the Falcons on Sunday, Ian Rapoport of NFL Network reports.
Morris didn't win the job in camp, losing out to rookie Kingsley Suamataia. However, Suamataia struggled Week 2 and allowed Bengals pass rusher Trey Hendrickson to get the best of him, leading to him being benched during the game. The Chiefs will now turn to the second-year pro to protect Patrick Mahomes' blindside.
