Detroit Lions franchise-tagged defensive end Ziggy Ansah will not reach a deal by Monday's 4 p.m. ET deadline to sign franchise players, league sources said Sunday.
Ansah's contract will expire after this season, when he will be scheduled to become a free agent.
Ansah has recorded 44 sacks in five NFL seasons, all with the Lions. He had 12 sacks last season, two years after posting a career-high 14.5 and making the Pro Bowl.
