Once a strength, the Detroit Lions defensive line now has plenty of holes. Help is on the way.

 The Lions signed defensive tackle C.J. Mosley to a two-year deal today (Wednesday), according to Adam Caplan of TheSidelineView.com.

  The 29-year-old Mosley had been a backup for his first seven NFL seasons. He started 13 games for the Jacksonville Jaguars last season, finishing with 2.5 sacks and 45 tackles. Both were career highs.

  He was drafted by the Minnesota Vikings in 2005. Mosley also played for the New York Jets and Cleveland Browns. In fact, it was when he played for the Browns in 2009, that Mosley hit Matthew Stafford hard enough to separate his shoulder near the end of the game.

  At defensive tackle, beyond starters Ndamukong Suh and Nick Fairley, the cupboard is nearly bare. Sammie Hill was signed by Tennessee as a free agent and Corey Williams is still on the market along with Andre Fluellen.

  Defensive end is also a need with Cliff Avril (signed with Seattle) and Kyle Vanden Bosch released. Jason Jones, who was signed as a free agent, is expected to start in Avril’s spot.  Willie Young will return, but Lawrence Jackson has not been re-signed. At least yet.
