The Cowboys called Pellerin up from the practice squad after Patmon was hurt against the Jacksonville Jaguars on Nov. 9, and he played in three games but did not record a tackle or pass breakup.
If Pellerin clears waivers, he could be brought back to the practice squad.
With Patmon and safety Jeff Heath (thumb) out, the Cowboys have not used a dime package in the last two games. Patmon has two defensive tackles and returned his only interception 58 yards for a touchdown against the Arizona Cardinals. He also has five special teams’ tackles.
“We’ll give him a chance to practice a little bit on Wednesday and see how he responds to that,” coach Jason Garrett said. “But he’s been a good player for us, and that package against certain teams and certain personnel groups has been something that we’ve used a little bit. So depending on what his availability is that might be a possibility.”
The Cowboys have an open spot on their 53-man roster with this move.
