Safety Jerome Couplin replaces CB Carmichael

PHILADELPHIA -- The Philadelphia Eagles signed safety Jerome Couplin off the Detroit Lions practice squad.

The addition of Couplin explains Tuesday’s subtraction of cornerback Roc Carmichael. The Eagles released Carmichael, who had been with the team since Nov. 18. Carmichael did not appear in a game this season.

The moves continue a bottom-of-the-roster shuffle in search of talent in the secondary. The Eagles added former Jacksonville safety Paul Prosinski on Nov. 3. Prosinski has developed into a solid special-teams player for the Eagles.

The 6-foot-2, 215-pound Couplin played college football at William & Mary. He was not taken in the 2014 NFL draft. Couplin signed with the Detroit Lions and made their roster coming out of training camp. He appeared in eight games for the Lions before being released and then signed to their practice squad.

The Buffalo Bills signed Couplin last month, but released him. He returned to Detroit and was on the practice squad up until signing with the Eagles.
