The Jets have added CB Dexter McDougle, S Ronald Martin, RB Dominique Williams and RB Raheem Mostert to their practice squad. The first three players spent the preseason with the Jets while Mostert was with the Browns this offseason and preseason. All were waived Sept. 4.

Also, TE Brian Parker, acquired on waivers from Kansas City on Sunday, has been waived/failed physical.

McDougle, a Maryland product who was the Jets' third-round selection (No. 80 overall) in the 2014 draft, appeared in 14 games last season. He saw most of his action on special teams, although he played on defense against Washington, at Oakland and at home vs. Miami. He spent his rookie season on IR with a knee injury.

Martin, acquired on waivers from Seattle last year, spent time on the Green & White's practice squad in 2015 and also played in eight games, all of his plays coming on special teams. He played in the Jets' last three preseason games this summer, totaling 147 defensive snaps.

Williams was signed to a reserve/future contract by the Jets in January after stretches with the Vikings and Cardinals in 2014 and '15. He saw action in the preseason opener against Jacksonville and had three carries for 17 yards.

Mostert, a top kickoff returner for four seasons at Purdue, entered the NFL with the Eagles as an undrafted free agent after the 2015 draft. He was acquired by three different teams on waivers that season — Miami, Baltimore and Cleveland and was with the Browns this year, rushing seven times for 47 yards, catching one pass for 7 yards, and returning two punts and four kickoffs in the preseason.
