Dallas Cowboys offensive lineman Chuma Edoga is expected to miss at least a month due to a significant toe injury sustained in the preseason opener against the Los Angeles Rams. This injury opens the door for rookie first-round pick Tyler Guyton to potentially start at left tackle, as confirmed by coach Mike McCarthy. Edoga, who played a crucial role as a versatile guard and tackle last season, was seen in a protective boot after the game and will likely start the season on injured reserve. The Cowboys drafted Guyton with the hope he could replace Tyron Smith, who signed with the New York Jets. Additionally, rookie Cooper Beebe will get first-team reps at center, while undrafted player Brock Hoffman has taken most first-team snaps during the offseason. The injury significantly impacts the depth and versatility of the Cowboys' offensive line.
