The Ravens moved Gwyn (lower leg) to injured reserve Saturday.
This move was anticipated after Gwyn was diagnosed with a fractured fibula earlier in the week and given a 2-to-3 month return timetable. Ethan Pocic (knee) also landed on injured reserve Saturday, so Baltimore will have to rely on rookie first-rounder Olaivavega Ioane to handle center duties Sunday versus Tennessee and for several weeks beyond.
