Also fitting given the 49ers’ injury-marred season: Quarterback Brock Purdy suffered an elbow injury when he was sacked with 1:36 remaining.

After the game, Purdy said he’ll get an MRI on Tuesday and said his elbow “doesn’t feel the best” and that it was “on fire” after he got hit. The 49ers did tests and ruled out a UCL injury — the injury that forced him out of the NFC Championship Game against the Eagles in January 2023.

After the 49ers rallied from a 17-point halftime deficit in January, the Lions overcame a 21-13 third-quarter hole on Monday.

And after a third-quarter fumble by Lions running back Jahmyr Gibbs was part of the 49ers’ spirited rally in the NFC title game, Purdy threw two second-half interceptions, both of which led to touchdown drives.

Finally, after Detroit head coach Dan Campbell went 0-for-2 on fourth down in the second half in the NFC title game — whiffs that were critical to the 49ers’ comeback — the Lions went 2-for-3 on fourth down Monday.

The 49ers had season highs in first downs (25) and yards (475). But they lost for the fifth time in their past six games because they couldn’t stop the NFL’s second-ranked offense, which had 439 yards and went 11 of 17 on third and fourth down.

Lions QB Jared Goff completed 26 of 34 passes for 304 yards with three touchdowns and Gibbs (117 rushing yards) became the fifth player in the past six games to rush for 100-plus yards against the 49ers. Before the current stretch, the 49ers hadn’t allowed a 100-yard rusher in their previous 55 games, the longest streak in the NFL since 1955.

Niners kicker Jake Moody continued his second-half slump by missing field goals of 51 and 58 yards and missing his first extra point of the season after Joshua Dobbs scored on a TD run in the final minute. Moody, who had made his first 29 extra-point tries, has made just 10 of his past 18 field-goal attempts.

“We weren’t able to slow them down enough on defense,” 49ers coach Kyle Shanahan said. “That’s a real good offense, but we still have to slow them down a little bit more. That was the difference in the game. We had to win in it in a shootout. I thought the difference was our two turnovers.”

INJURIES

Lions: RT Penei Sewell went to the locker room early at the end of the first half to get a thumb injury checked out but there is no concern about his status.

49ers: Purdy left late in the fourth quarter after hurting his throwing elbow on a sack. Purdy said his elbow “doesn’t feel the best” but initial testing showed his surgically repaired ligament from an injury sustained in the 2022 NFC title game against Philadelphia is fine.
