IRVING, Texas – Looking to boost their coverage teams in a week in which they face Seattle’s Leon Washington, the Cowboys have signed cornerback LeQuan Lewis off waivers from the New York Jets.

Lewis (5-foot-11, 187 pounds) had been on the Jets practice squad before his release. He made three tackles in the preseason for New York. He went to camp last year with Tennessee. He replaces tight end Colin Cochart, who was released Tuesday, on the Cowboys’ 53-man roster.

Washington is among the most dangerous kick and punt returners in the league. He had an 83-yard kickoff and a 52-yard punt return in the Seahawks’ Week 1 loss at Arizona.

The Cowboys’ coverage units should receive a boost this week with the return of safety Danny McCray, who missed the Giants game in Week 1 with a stinger. Linebacker Kyle Wilber (finger) could also return to action this week.

"We had a fourth tight end who we signed based on Witten's health and Witten obviously was healthy enough to play last week," coach Jason Garrett said Wednesday morning in explaining the roster move. "We anticipate him being able to practice and play this week. We signed LeQuan Lewis from the Jets, he was actually released by the Jets and he was a guy we targeted as a special teams guy. So we'll bring him in here and see how he fits into our 53-man roster and maybe our 46-man roster this week."
