Mark Nzeocha will be an active member of the Dallas Cowboys' 53-man roster.

The rookie linebacker has spent the entire season on the NFI list rehabbing his way back from an ACL injury suffered during his senior season at Wyoming. To make room for Nzeocha, the Cowboys waived quarterback Kellen Moore on Tuesday.

The Cowboys are dealing with a string of injuries at the linebacker position. Sean Lee is going through concussion protocol and is doubtful for Sunday's game. Anthony Hitchens is dealing with an ankle injury and missed practice on Wednesday. Hitchens will be limited at practice.

Head coach Jason Garrett addressed the activation of Nzeocha during his Wednesday press conference.

"We anticipated him to be on this time table," Garrett said of Nzeocha's Week 10 activation. "He had an ACL surgery last year. We knew that it was going to take him time. We knew that we weren't going to see him in the offseason or training camp or the early part of this season. But he's worked very hard to come back and he's stayed very engaged with our team which has been a positive thing. He's looked good at practice the last couple of weeks, so hopefully he'll get a shot this week."

The Cowboys drafted Nzeocha in the seventh round of the 2015 NFL Draft. Nzeocha can aggressively take on blocks and has great defensive pursuit to the football.
