Funk was waived by the Lions on Tuesday.
Funk got some early-season run in the NFL with the Colts last year but was used mostly on special teams. He was cut by Indianapolis in early October, then had stints on the Dolphins' and Ravens' practice squads. Funk struggled to find running room for the Lions during the preseason, gaining just 62 yards on 22 carries, and he also hauled in three of nine targets for 29 yards and a touchdown in the passing game.
