The Ravens placed Buchanan (ACL) on injured reserve Saturday.

EDGE Analysis

Buchanan will miss the remainder of the 2025 campaign due to a torn right ACL suffered in Week 15 against the Bengals, so his placement on IR was anticipated. In Buchanan's stead, Trenton Simpson will now inherit a starting role at inside linebacker alongside Roquan Smith beginning Sunday versus the Patriots.
