Reiff, a first-round pick in 2012, started 69 of the 77 games he played for the Lions and likely will be asked to step in the departing Matt Kalil, who signed with Carolina on Thursday. The move reunites Kalil with his older brother, Ryan, the Panthers’ five-time Pro Bowl center.
With Reiff headed for Minnesota and Larry Warford signing with New Orleans, the Lions made a move to bolster their offensive line in acquiring former Wisconsin tackle Rick Wagner, a former fifth-round pick who started three seasons for Baltimore.
Detroit also signed former Oakland cornerback D.J. Hayden and Tampa Bay defensive tackle Akeem Spence, who had 19 tackles and a ½ sack in 16 games last season.
After releasing Jay Cutler earlier this week, the Chicago Bears have signed former Buccaneers quarterback Mike Glennon, who threw for 4,100 yards, 30 TDs and 15 INTs in four seasons in Tampa Bay.
The Bears also have added veteran safety Quintin Demps, cornerback Prince Amukamara, tight end Dion Sims and receiver Markus Wheaton after losing Pro Bowl receiver Alshon Jeffery, tight end Logan Paulsen and quarterback Brian Hoyer in free agency.
