You've heard the old joke about a team playing 12-on-11 when an official's calls seem to keep going against it.

On Monday night, the San Francisco 49ers really did have an extra defender in stripes.

In one of the weirdest plays of this NFL season, or any NFL season, Lamar Jackson took an intentional grounding safety after he tripped over a fallen official in the end zone and attempted a pass. The Baltimore Ravens probably weren't too pleased about that comical predicament.

Umpire Alex Moore was well behind the play, as usual, when Jackson dropped back to pass. Jackson was under pressure right away and kept retreating. Moore kept retreating too, but he couldn't keep backpedaling to stay behind Jackson, who was trying to escape the rush at full speed. Moore stumbled as he was going backward and right into Jackson's path in the end zone. Jackson tripped over the umpire and had to try to unload the ball before he went down.

Because the ball didn't get past the line of scrimmage, it was intentional grounding. Because the penalty happened in the end zone, it was a safety. That's horrible luck for Baltimore and quite a break for the 49ers.

Moore was seen later on the ESPN broadcast laughing and smirking in a "Wanna get away?" type of reaction. There's not much else he could have done, and sometimes the officials on the field become an unwanted part of a play. They position themselves so they rarely are in the way of players, but sometimes it's unavoidable.

The bad break compounded for the Ravens when Niners got the ball back and scored a field goal to go up 5-0.

Fortunately for the Ravens, that safety ended up being a small drip before the dam broke in their favor. They proceeded to outscore the Niners 33-14 over the next three quarters to post the impressive win of the NFL season.

After the game, Jackson said Moore apologized to him, though he also made sure to note he would have escaped had it not been for the unplanned obstacle:

Moore wasn't a well-known official before Monday night. He got plenty of attention early during one of the most anticipated matchups of the NFL season. It's not a tackle he wanted to make, but it at least ended up barely mattering.
