What happened: Dallas Cowboys linebacker DeMarvion Overshown took responsibility and apologized to the team after drawing an unsportsmanlike conduct penalty in Sunday's 27-23 victory over the Indianapolis Colts. Sidelined by a hamstring strain, Overshown entered the field in street clothes during a live ball to celebrate a takeaway. He acknowledged he was unaware that inactive players were prohibited from joining the celebration until Dee Winters alerted him.

Why it matters: The penalty cost Dallas yardage during a tight contest, though the defense held on to push the Cowboys to 4-5 on the season. The lapse drew public scrutiny from team leadership and veterans, reinforcing discipline standards as Dallas fights for playoff positioning in the NFC.

What to watch: The Cowboys continue regular-season preparations as Overshown works toward clearance from his hamstring injury.
