Decker's availability was a big question, but he practiced well Saturday and experienced no setbacks during pregame warm-ups. He missed last week's loss to the Philadelphia Eagles after spraining a posterior cruciate ligament in his left knee in Week 2.
Decker was a big part of the passing offense in the first two games, catching 10 passes for 134 yards and two touchdowns.
His return gives the Jets (2-1) their full complement of skill position players for their first divisional game. Running back Chris Ivory, who didn't play last week because of a strained quadriceps, is expected to play after practicing all week.
