Davis, who played collegiately at Central Florida, signed with New York as an undrafted free agent on May 9. As a senior, Davis notched 72 tackles and eight sacks and earned first-team all-Conference USA honors as a defensive lineman.
The Jets, who host Pittsburgh on Sunday, are at their 53-player roster limit.
