BALTIMORE -- Lamar Jackson was solid in Baltimore's biggest game of the season so far.
Then, after one of the star quarterback's rare slip-ups, one of his teammates delivered the play of the day.
Jackson threw three touchdown passes and Marlon Humphrey scored on a fourth-quarter interception return to help the Ravens pull even with Pittsburgh atop the AFC North with a 34-17 victory Saturday against the Steelers.
Pittsburgh (10-5) would have clinched the division with a victory, but now the teams are deadlocked after the Ravens (10-5) won for just the second time in the last 10 games in this series. Baltimore clinched a playoff berth. The Steelers had already done so.
"It was cool to get a pick-6, but clinching a spot in the playoffs, to beat the Steelers, I'm just happy that the guys came in, put in the work, and we just took care of business," Humphrey said. "I felt that this team has had our number over the years. Just take care of business, man. I felt like the performance we put on wasn't perfect, but I felt like that's what we were supposed to do."
Russell Wilson threw two touchdown passes, the second of which tied the game at 17 with 5:14 left in the third quarter. Jackson answered with a 7-yard scoring strike to Mark Andrews, and after Pittsburgh turned the ball over on downs, a 44-yard run by Derrick Henry put the Ravens in the red zone.
That drive came to nothing when Jackson was intercepted for just the fourth time this season, but then Humphrey -- who was celebrating the recent birth of his son Duke -- picked off Wilson and went 37 yards to the end zone to give Baltimore a cushion in a series that's been razor-thin of late. The previous nine games between the Steelers and Ravens were decided by seven points or fewer.
"My whole family's in town to help out with my wife and everything," Humphrey said. "I was texting her before. I'm supposed to go pick her up from the hospital, discharge her with the baby. So there's a lot of just great things that happened this week."
Jackson improved to 2-4 against Pittsburgh as a starter. This was his first time facing the Steelers at home since 2020.
"I feel like we've been busting our behind all season long, had ups and downs throughout this whole season, but to clinch a playoff against a great team like that, that's great," Jackson said. "That means we're moving in the right direction."
Henry rushed for 162 yards.
Both teams play on Christmas Day to wrap up stretches of three games in 11 days. Pittsburgh hosts Kansas City and Baltimore plays at Houston.
