The Dallas Cowboys used their Friday off from training camp to tweak the back end of the roster, signing running back Jashaun Corbin and waiving Dominic Richardson.
Richardson had been one of Dallas’ 11 undrafted free-agent additions after the 2026 NFL Draft, but he didn’t do enough during camp to hold onto his spot.
Corbin arrives with a little more NFL experience. He has appeared in six career games, all with the New York Giants in 2023, when he logged one carry for one yard and three catches for 12 yards while mostly contributing on special teams. He has also had time with the Carolina Panthers, Atlanta Falcons and New England Patriots.
His strongest résumé, though, comes from the UFL. Corbin led the league in rushing yards in 2025 with 514 and scored four rushing touchdowns for the San Antoni Brahmas, while also adding 18 receptions for 138 yards. He followed that up in 2026 with the Orlando Storm, putting up 438 rushing yards, 118 receiving yards and four total touchdowns, good for third in the league in rushing.
Even with that production, the path to Dallas’ 53-man roster looks steep. The Cowboys’ running back room is already crowded with Javonte Williams, Malik Davis, Jaydon Blue and Phil Mafah.
Davis, Blue and Mafah are all battling for the RB2 role, and it’s been a tight race. Blue has separated a bit and is expected to make the roster, with a real chance to jump Davis for the backup job. Mafah, meanwhile, has made a strong enough push that Dallas could keep four backs.
If Corbin does carve out a role, practice squad seems like the most realistic landing spot. Even there, he may need Mafah to miss out, since the former seventh-round pick would likely be Dallas’ practice squad back if he doesn’t make the team.
Corbin’s biggest competition for that spot may come from Israel Abanikanda, who has also turned heads in camp.
And Corbin still has time to make his case. Dallas has two joint practices and three preseason games left, giving him several more chances to show what he can do.

Cowboys Just Revealed Who Will Set The Locker Room Standard
The Cowboys have put a fresh layer of structure around the way they want their locker room to function this season, naming an 11-player Leadership Council made up of veterans and core pieces the staff believes already set the tone behind the scenes. It is a group built around positive influence, communication and professional habits, with Dak Prescott, CeeDee Lamb, Javonte Williams, Jake Ferguson, Tyler Smith, Tyler Booker and Quinnen Williams among the players expected to help define the standard day to day.
For Dallas, the significance is less about ceremony than alignment. The coaching staff is signaling that leadership is not being left to chance or reputation alone, and that the players chosen for this council will be leaned on to keep the culture steady as the season unfolds. With so many familiar voices in the room, the Cowboys are clearly betting that the strongest example can come from inside the locker room itself. [Read more 🡒]
Cowboys Camp Is Suddenly Creating Tough Roster Decisions
Training camp is starting to sharpen the Cowboys roster picture in more than a few spots, and its doing so with players who were never supposed to make life easy for the coaching staff. Brevyn Spann-Ford has pushed himself into the conversation for the backup tight end job by looking better as both a pass catcher and a run blocker, while rookie linebacker Jaishawn Barham has turned heads with his speed, range and physicality, enough to earn work with the first-team defense.
Ryan Flournoy has added to the squeeze by showing cleaner route running and more dependable hands, giving Dallas another receiver who looks capable of helping right away. For a team trying to sort out the bottom of the depth chart, that kind of progress creates a good problem, but it also means some players who seemed to be on the outside suddenly have a real path to the roster.

Cowboys Defense Is Already Feeling One New Voice At Camp
The first week of padded practices has given the Cowboys a better sense of what this camp might become, and a new voice is already settling in on the defensive side. Christian Parker has stepped into his role as defensive coordinator and, by the sound of it, the biggest early impression is not some schematic wrinkle but the way he has handled communication. For a team trying to sharpen itself in the middle of summer work, that kind of clarity can matter just as much as any headline-grabbing adjustment.
There are other camp notes worth watching around the roster, too. Tyler Guyton is showing progress entering his third season, according to teammate Terence Steele, while Dallas has also added Jashaun Corbin and continued to sort through the early competition elsewhere. Quarterback Joe Milton has drawn attention in the first round of roster projections as someone who has taken a noticeable step forward, but for now the more immediate takeaway is that the Cowboys are starting to see how a new defensive voice can shape the tone of practice.
