Isaiah Davis Ruled Out for Week 18 with Concussion

Jets RB Isaiah Davis (concussion) has been ruled out for Sunday's Week 18 game against the Bills. His absence, along with Breece Hall (knee) being out, means Khalil Herbert and Kene Nwangwu will handle the primary backfield duties for New York in the regular-season finale. The team may also elevate Raheem Blackshear from the practice squad.
