Allen Park — The Lions were down to their last healthy tight end in Sunday's game against the Saints and have bolstered the position ahead of their trip to London this week.
They announced they have signed veteran tight end Kellen Davis, who played at Michigan State, and released backup safety Jerome Couplin.
Davis, 6-foot-7, 265 pounds, is in his seventh season, playing five with the Bears and last season as a backup with the Seahawks, along with Lions receiver Golden Tate. In 2012, Davis had 19 catches for 229 yards and two touchdowns and had five touchdowns the previous season.
The move was necessary, as starter Brandon Pettigrew was hobbled in Sunday's win over the Saints and rookie Eric Ebron (hamstring) and Joseph Fauria (ankle) both missed the game. The only other healthy tight end was Jordan Thompson, who was signed from the practice squad on Saturday.
They also signed receiver Ifeanyi Momah — listed at 6-foot-7, 239 pounds — to the practice squad, replacing Thompson. Momah, who played at Boston College, got some first-team reps with the Eagles in the preseason but was released after a disappointing camp.
