Mitchell was signed to the Cowboys’ practice squad on Dec. 2. He should get a chance to serve as the Cowboys’ nickelback Saturday against the New York Jets.
The Cowboys decided to move on from Patmon after last week’s loss to the Green Bay Packers. He has since joined the Miami Dolphins’ practice squad.
Mitchell was one of the Cowboys’ five seventh-round draft picks last year but was among their final cuts. He joined the Chicago Bears and was added to the active roster but did not play in a game. He played in the first five games this year before suffering a hamstring injury. He was cut, added to the Bears’ practice squad and released Nov. 23.
“We’ve liked him right from the start,” coach Jason Garrett said Thursday. “That’s why we drafted him and brought him in here, and he showed us a lot of the traits that we liked in the draft once he was here. It’s a competitive position, and it’s a hard position for a guy to make. I think he was a victim of that as much as anything else. All the same things we liked -- his instincts, his physicalness -- still exist, and I think he’s a more mature player now than he was, having been in a couple of systems and hopefully learned a little bit there. So he’s had a good week of practice and we’re optimistic about how he can help us.”
