Matthew Stafford was 16-of-25 passing for 221 yards and a touchdown, while Kyren Williams ran for 89 yards and two scores on the ground, with one more receiving, as the Rams (1-2) ended a five-game home losing streak against the 49ers.
Niners quarterback Brock Purdy was 22-of-30 passing for 292 yards and connected on three touchdown passes with Jauan Jennings, who had 11 receptions for 175 yards. Jordan Mason rushed for 77 yards for San Francisco (1-2).
After getting a 33-yard field goal from Karty with just over six minutes left to pull within 24-17, the Rams then went on a three-play, 55-yard drive to score on a 3-yard run from Williams with 1:51 to play, tying the score at 24.
Los Angeles forced a San Francisco punt with under a minute to go, and rookie Xavier Smith returned the kick 38 yards to the 50-yard line. A 49ers pass interference penalty moved the ball to the San Francisco 19-yard line before Karty made the game-winner in his third NFL game.
Panthers 36 Raiders 22
Andy Dalton threw three touchdown passes and sparked what had been a dismal Carolina offence for a victory against host Las Vegas.
Dalton, a 36-year-old veteran who became a journeyman after beginning his career with the Cincinnati Bengals, replaced 2023 No. 1 overall draft choice Bryce Young as the starting quarterback just three games into the season. Dalton completed 26 of 37 passes for 319 yards without an interception.
Chuba Hubbard ran for 114 yards on 21 carries and caught five passes for 55 yards and a score for the Panthers (1-2). Gardner Minshew completed 18 of 28 passes with an interception and a 13-yard TD pass to Jakobi Meyers in the fourth quarter for the Raiders (1-2).
Ravens 28 Cowboys 25
Derrick Henry rushed for 151 yards and two touchdowns on 25 carries and Baltimore survived a late rally by Dallas to earn their first win of the season in Arlington, Texas.
Cowboys quarterback Dak Prescott threw a 16-yard touchdown pass to KaVontae Turpin to pull Dallas within 28-25 with 2:53 remaining. However, the Cowboys were out of timeouts, and a 10-yard run by Lamar Jackson after the two-minute warning sealed the win for Baltimore (1-2).
Jackson threw for 182 yards with a touchdown and ran for 87 yards and a score. Prescott completed 28 of 51 passes for 379 yards with two touchdowns. Tight end Jake Ferguson hauled in six catches for 95 yards for the Cowboys (1-2).
