Rod Coleman caused the fumble after sacking quarterback Vinny Testaverde with the Jets facing first down at their 37-yard line. Davis was in the right place at the right time, but the same could not be said of Smith, who hobbled off the field on the previous series with a dislocated big right toe.
Smith made it to the sideline, but team officials had to drive him to the locker room in a cart. The 10th-year veteran did not return.
In a Week 2 loss at Seattle and a Week 3 win at Buffalo, Davis started at left end and Patrick Kerney switched sides as Smith nursed a sore quadriceps. Davis had his first career sack against the Bills.
