Stefon Diggs turned a 10-yard touchdown into a costly moment for the Washington Commanders, then drew an unsportsmanlike flag for using the goal post as a prop. The score had just been cut to 17-15 in Week 1 against the Philadelphia Eagles when the celebration stopped being a highlight and became a penalty.
That is why the Stefon Diggs penalty is being replayed now: it came at the exact point where Washington had a chance to keep the game alive. The Commanders trailed 17-9 with 10 minutes left before Diggs scored, and his touchdown tightened the margin enough that one more push could have forced a tie. Instead, the flag left Washington without the clean extra step it needed in a game it would go on to lose.
Diggs said afterward that he simply forgot the rule. “As soon as I wrapped my arms around it I was like this: ‘Oh I forgot,’” he said. “Back in the day, you know, I’ve been playing a long time, you used to could do that.” He added that he needed to stay current on the rules and “I got to be better.”
The problem is that the celebration he reached for has been illegal since 2006. Diggs entered the NFL in 2015, long after the league barred players from using the goal post as a prop, which made his response less a forgotten old habit than a reminder that experience does not excuse a flag. He also said he had just scored his first touchdown with his new team, which helped explain the emotion of the moment without changing the ruling.
That is the part Washington cannot get back. Diggs’ touchdown made the game close enough to matter, but the immediate penalty kept the Commanders from turning the drive into a cleaner path to a tie. Whether the flag alone decided the result is not the point; it was the kind of mistake that can shrink a team’s margin in the final minutes and leave one celebration carrying more weight than the score itself.
