Kiwanuka, 31, may have played his last game with the Giants after nine seasons and two Super Bowl titles. He would count $7.45 million against the 2015 salary cap, and the Giants could realize savings of almost $5 million by cutting him. Kiwanuka has 38.5 sacks in his career, 2.5 this season.
Ayers started for Kiwanuka Sunday in Jacksonville and was tied for the team lead with five sacks. Snyder started in the loss to Dallas.
