With three guards opting out of the 2020 NFL season on the Browns, the team added some depth for training camp with the signing of OG Michael Dunn (6-5, 315 lbs).
Dunn was originally an undrafted free agent in 2017 who signed with the Rams. He has spent time on the practice squads of the Rams and Jaguars, and also was in camp with the Dolphins last year. He has seen recent playing experience in both the AAF and the XFL, which might be where the Browns saw enough to give him a chance.
