Ansah will make $17.143 million in the 2018-19 season, signing the offer after the Lions put the franchise tag on Ansah in late February.
The Lions drafted Ziggy fifth overall in 2013. The 6-foot-5, 271-pound defensive end is set to enter his sixth NFL season.
He recorded 39 tackles, including 12 sacks, over 14 games in the 2017-18 season. He’s tallied 44 sacks in his five pro seasons.
Ansah made a combined $6.7 million in his first four seasons before garnering $12.7 million last season, according to Spotrac.
Because of the franchise tag, NBC Sports reports Ansah would draw $20.572 million in 2019-20 if the Lions wish to retain him and keep him from entering unrestricted free agency.
In his 2012 senior season at BYU, Ansah tallied 13 tackles for loss, 4.5 sacks, nine pass breakups, one interception and one forced fumble while spending time at defensive end, outside linebacker, and nose tackle for a historic Cougars defense.
