On the final play of the game last Sunday at Ford Field between the Detroit Lions and the Pittsburgh Steelers, Lions Pro Bowl wide receiver Amon-Ra St. Brown knew going into the pivotal fourth and goal that if he didn’t get into the end zone, he was going to lateral the ball to a teammate.

Ultimately, he did just that, pitching the ball to quarterback Jared Goff, who tumbled into the end zone for what many thought was the game-winning score.

But there were just a few slight problems with that. St. Brown had a pass interference penalty on Steelers safety Jalen Ramsey in the end zone to get open for the catch. Then, lost in all the chaos of the final moments, St. Brown — in an appearance on the latest episode of his podcast with his brother, Equanimeous St. Brown — admitted that he didn’t know the NFL rules and was confused as to why the Lions didn’t get another play after the penalty.

“I knew there was a flag. I knew it was probably OPI, but I was like, ‘We’re gonna get another chance,’ like one more shot,” St. Brown said of the final moments against the Steelers, according to video via the show’s YouTube page. “I thought we were gonna get one more play, but the game was over.

“I guess it’s a rule. Never heard of that rule, but you learn new shit every day.”

St. Brown is referring to the in which a penalty on the offense at the end of the half or a game does not earn an untimed down. Since St. Brown was called for offensive pass interference and the clock ran out during the play, the game was immediately over due to the offensive penalty.

That’s a pretty common rule, one that is well-known. The fact that an NFL receiver of St. Brown’s caliber didn’t know it was a rule is a bit baffling.

To his credit though, he continued to accept the penalty, citing that he did have a bit of a push-off and understood the call. After the game, St. Brown was all class. He took responsibility for the penalty and stated that the game didn’t come down to one play as the Lions had plenty of other opportunities to get the results that they wanted, but didn’t.

Still, it didn’t take away from the craziness of the game, which saw two offensive pass interference penalties late go against the Lions.

“Bro, like this was so weird. But it was one of the craziest games ever, bro,” St. Brown added. “And the OPI, I mean, yeah, I guess I low-key did push off. But I don’t know. For those two back-to-back OPI calls like that was crazy.”

It was a crazy sequence, but fortunately it went in the Steelers’ favor. How the officials handled things at the end of the game was a bit strange, initially calling a touchdown and setting off a celebration in Ford Field. But in the end, Carl Cheffers’ crew got it right.
