A source told the Post that the deal is for four years with a signing bonus of $45,896.
Allen played both linebacker and safety during his career at South Carolina, but projects as a safety in the NFL. The Jets were excited that he was still on the board when they picked at No. 242 because they feel he has the talent of a mid-round selection.
With the Allen signing, the Jets have now inked five of their eight picks from the 2012 NFL Draft. Quinton Coples, the team's first-round choice out of North Carolina, has yet to sign.
