SAN FRANCISCO — Vernon Davis caught touchdown passes of 61 and 35 yards and finished with a career-best 180 yards receiving, leading San Francisco to its third straight victory.
Colin Kaepernick threw for 252 yards and Frank Gore ran for 101 yards on 25 carries.
Kendall Hunter ran for a 6-yard touchdown that sealed it for the 49ers (4-2) with 6:35 remaining.
Rookie safety Eric Reid made his team-leading third interception and also recovered a fumble to stop an Arizona drive deep in 49ers territory in the third quarter. San Francisco forced four turnovers for the second straight game.
Arizona (3-3) lost star defensive end Calais Campbell to an apparent right leg injury late in the game.
CHIEFS 24, RAIDERS 7
KANSAS CITY, Mo. — Jamaal Charles ran for two touchdowns, the Kansas City defense harassed Oakland quarterback Terrelle Pryor into throwing three second-half interceptions and the Chiefs remained unbeaten.
After winning just twice last season, Kansas City (6-0) continued the second-best start in franchise history. The Chiefs won their first nine games during the 2003 season.
The Chiefs piled up 10 sacks while ending a three-game skid to the Raiders (2-4), and a six-game losing streak against them at Arrowhead Stadium.
Pryor threw for 216 yards and a touchdown, but his interceptions proved costly.
The first led to Charles’ go-ahead touchdown run, the second led to Ryan Succop’s fourth-quarter field goal.
