Horn suffered a broken right foot during Thursday's game against the Texans, Jeremy Fowler of ESPN.com reports.
The team didn't reveal an initial timetable for Horn's return, but we can expect to rookie to miss significant time. This is a major loss for the Panthers, who expended the No. 8 overall pick on Horn back in April. Through three games, he has posted five tackles (three solo), an interception and a pass breakup. Rashaan Melvin stepped in at corner Thursday. Melvin or A.J. Bouye -- who was scratched Thursday -- will start in Horn's place
