The Detroit Lions released veteran tight end Tony Scheffler and signed veteran offensive tackle Barry Richardson, the team announced Tuesday.
Scheffler had been sidelined the last two weeks with a concussion, but he was cleared to return from the concussion he suffered Oct. 6 against the Green Bay Packers. He had been with the Lions since the 2010 season.
Richardson is a five-year veteran and started all 48 games over the past three seasons with the Kansas City Chiefs and St. Louis Rams, 47 at right tackle. The 6-foot-6, 319-pound tackle signed with the Tennessee Titans this offseason, but was released after training camp.
