Darnold, who was the No. 3 overall pick in the 2018 NFL draft, went 4-9 as a starter his rookie season. The Jets, who are 0-4, lost the season opener to the Bills 17-16 with Darnold at the helm. He threw for 175 yards and a touchdown in that game. The Jets are also expected to get middle linebacker C.J. Mosley back after missing three games with a groin strain.
The Cowboys (3-2) have lost two consecutive games, including last week to the Packers, 34-24.
