Late in the fourth quarter of Sunday's 20-17 win over the rival Pittsburgh Steelers, the Ravens defense experienced a play that, had they lost, would have topped an already-long list of devastating plays that cost them games this year.
With the Steelers trailing by 10 points and just over seven minutes remaining in the AFC North showdown at M&T Bank Stadium, a pass went through Pittsburgh wide receiver Antonio Brown's hands and was intercepted by cornerback Jimmy Smith.
Smith returned the ball 101 yards down the sideline for a touchdown, setting off a celebration with the rest of the Ravens secondary and a similar scene around the stadium.
But a pre-snap penalty on outside linebacker Courtney Upshaw cost the Ravens those six points. Luckily for them, it wasn't worse.
Upshaw was in coverage on the Steelers' tight end bunch formation on the right side of the offensive line, and facing away from the football. His foot was almost even with the ball on the line of scrimmage, and he was flagged.
"I've just got to be aware of my alignment," Upshaw said. "A lot of times the guys, they'll warn you and tell you that, 'You were close on that last one, so back up,' or [I will] check the sideline and they'll back you up. But that's on me.
"We were so tight to the end zone, I was just trying to make sure that my guy wasn't the guy that caught a touchdown pass. That was a bad thing that once the play was over, Jimmy going to the house, and to see there was a flag and it was on me."
Coach John Harbaugh didn't comment on the play specifically, only noting that they responded to the play and didn't let it cost them the game the way other impactful, let-down plays have this year.
Pittsburgh scored a touchdown on a 2-yard run by DeAngelo Williams shortly after the penalty, but the Ravens held on.
When asked about it after the game, Smith wasn't happy to be deprived of the interception or his second touchdown of the season, but laughed it off when asked if Upshaw owed him dinner.
