The Panthers signed DT Ron Fields and OL Reggie Wells on Tuesday and officially placed MLB Jon Beason on injured reserve.
Fields spent training camp with the Dolphins before being cut. He made 22 tackles in 16 games last season for the Broncos.
Wells played in eight games, with one start, last season in Philadelphia after spending the first eight seasons of his career with the Cardinals. He started every game from 2006-2009.
