NFL Network's Mike Garafolo reports free agent DT Earl Mitchell is scheduled to visit the Seahawks, 49ers, Falcons, and Broncos.
He will begin his rounds next week. Mitchell played for new Broncos coach Vance Joseph in Miami last season, so they might be the early favorites. Mitchell will be a quality low-cost signing if he can stay healthy.

Mitchell played NT for Kollar/Phillips in Houston and obviously has a more recent connection with Joseph in Miami. Clearly he is thought of pretty highly around the league with this many visits lined up.
