The Lions placed WR Titus Young on injured reserve and signed S Tyrell Johnson and WR Kris Durham.
Young has not been with the team for the past few weeks after head coach Jim Schwartz sent him home from the team facility. In his 10 games, Young had 33 catches for 383 yards and four touchdowns. He was listed with a knee injury at times this season.
Johnson spent the preseason with the Dolphins after playing for the Vikings the previous four seasons. He played in 11 games with three starts last year, making 28 tackles.
Durham, who was promoted from the practice squad, adds depth at wideout, as Lions WR Ryan Broyles tore his ACL in Sunday’s loss to the Colts.
