Coach Matt Rhule said Monday that Horn (foot) is expected to be put on injured reserve and be sidelined for an extended period, David Newton of ESPN.com reports.
Horn was looking at a 2-to-3 month absence after the initial diagnosis of his broken foot. It's unclear if the 2021 No. 8 overall pick has elected to undergo surgery or not, but it was rumored that he may miss the entire season if he went that route. The Panthers recently signed Rashaan Melvin to their active roster and made a trade for CJ Henderson to prepare for Horn's lengthy absence.
