The Thursday Night Football game between Vikings and Rams ends with a glaring missed facemask penalty

The Los Angeles Rams' final shot in Thursday's 30-20 win over the Minnesota Vikings was a pretty obvious miscue.

Trailing by eight points with 1:46 left and no timeouts, the Vikings had to drive 95 yards for a TD and a two-point conversion to send the game into overtime. They didn't get very far as Rams linebacker Byron Young beat two blockers, sacked Sam Darnold and scored on a safety.

However, just watching it, it was pretty clear that Young had taken Darnold down by grabbing and dragging his facemask, which should have given the Vikings new life with a 15-yard penalty.

Another replay only highlighted how bad that missed call was. Darnold's head was pulled 90 degrees to the left as he was knocked to the ground:

Unfortunately, missed penalties for wearing face masks are not verifiable.

The penalty was so obvious that Young grabbed his head after the play as if he had made a mistake instead of sealing the game for Los Angeles. Instead, the Rams got two points and the ball, ending a rare hard-fought Thursday Night Football game.

You know it's a bad mistake when the officials don't even try to deny it after the game. Speaking to a pool reporter, referee Tra Blake essentially said none of the referees actually saw Young beat Darnold:

Vikings players and coaches were visibly unhappy when the replay was shown, and some NFL players watching weren't thrilled either:

It should be noted that this play did not cost the Vikings the game, just the chance to make it a game again. Even if the facemask were called, Minnesota would still have 80 yards to cover in one minute and 36 seconds, not to mention the two-point attempt and overtime. There were many other reasons why the Vikings lost, such as Matthew Stafford's four touchdown passes.

Still, it's a poor way to end a game and an argument could be made that face mask penalties should perhaps be reviewable. On the other hand, an even more dramatic play by the Rams was the impetus for making pass interference calls reviewable, and it ended so badly that the NFL abandoned it after one season.
