Rams head coach Sean McVay said Harris will require season-ending surgery to address a torn ACL and MCL in his knee, Stu Jackson of the Rams' official site reports.
Harris sustained the injury Sunday in the Rams' loss to the Titans while covering on a punt return in the first half. The 2021 fourth-round selection had mainly contributed on special teams outside of 15 snaps on offense between Weeks 6 and 8. Given the nature of his injuries, the 6-foot-5 tight end could struggle to gain clearance ahead of training camp in 2022.
