​DETROIT, MI – DECEMBER 04: Dallas Cowboys head coach Brian Schottenheimer walking the sideline near the end ofthe fourth quarter during the game between Dallas Cowboys and Detroit Lions on December 4, 2025 at Ford Field in Detroit, MI /CSM Detroit United States – ZUMAc04_ 20251204_zma_c04_045 Copyright: xAllanxDranbergx ©IMAGO/ZUMA Press WireDeMarvion Overshown did not even play last Sunday, and he still managed to cost the Cowboys 15 yards. Now a longtime Cowboys insider wants to know if Dallas will do anything about it.“If [Brian] Schottenheimer’s #Cowboys take discipline seriously? Overshown does not start on Sunday against the #49ers,” Mike Fisher wrote on X.The 49ers come to AT&T Stadium on Sunday, and the Cowboys linebacker is trying to get back on the field. Here is how he ended up at the center of a discipline debate.Overshown was inactive for the Week 9 Colts game with hamstring and back injuries. But he ran onto the field in street clothes to celebrate a fourth-quarter fumble recovery. That drew an unnecessary unsportsmanlike conduct penalty on the Cowboys, adding to an already eventful game for the team; Dallas was flagged a whopping 14 times!With discipline and roster decisions looming before a crucial divisional clash, see how the Cowboys handle internal accountability.

He also said he apologized right after the game and called the moment “a lesson learned.” He wasn’t expecting a penalty, particularly because he thought it was hardly causing trouble. It wasn’t until Dee Winters told Overshown that he couldn’t be on the field that he knew.“It’s not an indictment on Schotty. It’s on me as a player. I own it.”Head coach Schottenheimer did not hide his feelings, either.“Totally unacceptable, and it won’t happen again,” he said, adding that he spoke to Overshown. No fine or other formal punishment has been reported for the linebacker as of now.A stern talk is one thing, but a seat on the bench is a message the whole locker room would notice. Dak Prescott also had his thoughts on the issue.“I spoke my mind, and I think I don’t think I’ve ever been short or shy in a moment when it’s you know truly, truly bothered me,” he said. “And yeah, that was just a big play…the turnover happened and a flag comes out, and, yeah, it’s just like we did some great stuff here; let’s not minimize it.”There is a second chapter here. Ahead of that Colts game, the NFL handed Overshown a punishment. He was fined $9,528 for use of his helmet on Cardinals running back Bam Knight. He was ruled out with a concussion.No flag was thrown on the play. Oversho
