So, the NFL might as well have put a Super Bowl emblem on the plate next to the cranberry sauce when CBS revealed that the Kansas City Chiefs will be the Cowboys’ Thanksgiving opponent this year.

However, someone else posted something that took over the attention just as that news was beginning to go viral. A player who has yet to make a regular-season appearance. An individual whose last day of service was August 19, 2023. Now, though? Perhaps he just marked the date of his return with a permanent marker. DeMarvion Overshown. Reposting the NFL Thanksgiving post from CBS to his Instagram account, the Cowboys linebacker added the casual six words, “Oh yeah, I’m active in this.” No update on rehab. No news release. Only the sound of a siren. A trailer for the return of a linebacker who had every reason to vanish following the events of August.

Because Overshown’s ACL was not only torn. His PCL, MCL, and ACL were all torn. Each of the three. The triple threat of knee destruction in medicine. The type of ailment that causes rookies to disappear into rehab anonymity and training staff to whisper. Overshown, though? He never disappeared. Wearing that iconic No. 0 shirt, with a brace on his knee and a fire in his eyes, he has been there on the sidelines, in the locker room, and during team meetings. The Cowboys didn’t simply put him away; they kept him involved, and he continued to make noise.

And now? DeMarvion Overshown may be preparing a comeback in front of the biggest regular-season crowd of the year when the defending Super Bowl champions enter AT&T Stadium on Thanksgiving Day. And what if Agent Zero is, in fact, playing that game? Then, Mahomes needs to be aware of his blind spot. Because this isn’t your typical season matchup. For the first time since 2006, the Chiefs will play on Thanksgiving, and the NFL is combining its two most well-known brands into one. This game could surpass the all-time Thanksgiving viewership record, which the Cowboys themselves established in 2022 (42.1 million viewers), as Mahomes and Dak are scheduled to square off.

DeMarvion Overshown’s resurrection could redefine Schottenheimer’s defense

In 2024, DeMarvion Overshown did more than just ‘flash’—he was dominant. The linebacker recorded 90 tackles, 5 sacks, a pick, and a forced fumble in just 12 games. He became one of just five players in the league to record more than 90 tackles and five sacks during that time. All while recovering from a 2023 ACL tear.

Overshown’s comeback is now more about reloading than rehabilitation because Brian Schottenheimer is taking over defensive play-calling and adding new elements to a Dan Quinn-style framework. He’s not just getting back to work; he’s joining a defense in dire need of his leadership, ferocity, and range.

“Lil bro” is how Micah Parsons referred to DeMarvion Overshown. Now, the Cowboys’ defense that faltered in the latter part of 2024 might be revived by little bro. Overshown became the first Cowboys player to wear jersey No.0, given to him this offseason. He wore the same number at Texas, a reference to the supporters who called him ‘Agent Zero’ during his Longhorn days.

In case that wasn’t enough motivation, Overshown’s statement to Kay Adams, “That was just the tip of the iceberg. Like we ain’t seen nothing yet,” still rings true today. Even though Thanksgiving is still months away, Overshown’s post has already changed the course of events. From ‘Will he return in 2025?’ to ‘He’s back, Circle Nov. 27.’ That comeback might also be the surprise Christmas present Dallas didn’t realise it needed, according to Schottenheimer. Because every offence is on alert when Agent Zero is in action.
