Horn (concussion) has been ruled out for Sunday's game against the Rams, Joe Person of The Athletic reports.
Horn suffered the concussion in last Monday night's loss to the 49ers, and he'll now miss the Week 13 date with Los Angeles, significantly upgrading the matchup for both Puka Nacua and Davante Adams. With Horn sidelined, Akayleb Evans and Robert Rochell are likely to play elevated snaps at cornerback.
