JUSTIN REID (MOMENTARILY) MAKES IT RIGHT FOR ANDY REID

One play after Andy Reid greenlit a failed fourth-down punt fake on the Chiefs’ opening drive, safety Justin Reid — no relation — made it right with an interception.

Facing fourth-and-2 at its own 45-yard line, Kansas City sent its punting unit out, but the snap went to rookie safety Jaden Hicks, who ran into a wall and got tackled a yard short of the sticks giving San Francisco some early momentum.

49ers quarterback Brock Purdy rolled out to the right and tried to float a ball into George Kittle on the first play after the special-teams stop, but safety Justin Reid jumped the route, picked off the pass and gave the ball right back to the Chiefs’ offense.

Six plays later, Mahomes returned the favor when he tried to drive a throw into Jody Fortson on a slant route only to have San Francisco defensive tackle Kalia Davis paw the ball into the air and intercept it right back.

ROLAND-WALLACE ROBS PURDY

The 49ers had all the momentum and seemed destined to retake the lead midway through the third quarter, but Chiefs undrafted rookie cornerback Chris Roland-Wallace had other ideas.

Roland-Wallace, who played four seasons at Arizona then finished his college career at USC last season, played only one defensive snap in his first five NFL games, though he’s been a key contributor on special teams.

But he had the coverage on Ronnie Bell’s out route as San Francisco approached the red zone and Purdy floated a pass well over his receiver’s head along the sideline.

With a nifty double toe tap, Roland-Wallace secured the catch while falling out of bounds, creating a seismic momentum shift in Santa Clara.

Kansas City, which led 14-12 at the time Roland-Wallace picked off Purdy, marched 79 yards for another touchdown — Mahomes did the honors with a 1-yard scramble up the middle, running over safety Malik Mustapha at the goal line — to restore a two-score lead.

ANOTHER ROOKIE ROBBERY

Roland-Wallace wasn’t the only rookie defensive back to come up big for Kansas City.

Midway through the fourth quarter, San Francisco had reached the red zone and had a chance to make the game interesting before Purdy got picked for the third time.

With a spin move inside, defensive end George Karlaftis pressured the 49ers’ QB into a rushed decision and a bad throw.

Trying to force a ball into Chris Conley a yard deep in the end zone, Purdy instead rifled the pass into rookie safety Jaden Hicks’ midsection for his first career interception.

DEFENSE DOMINATES FIRST HALF AGAIN

Kansas City’s defense locked down San Francisco for most of the first half.

The 49ers had 56 total yards and two first downs on their first six drives.

Purdy was 3 of 9 for 38 yards with an interception to that point before a late field-goal drive pulled San Francisco within 14-6. He went 5 of 7 for 75 yards on the drive, which made it a one-score game at halftime.

Niners fullback Kyle Juszczzyk gained 14 yards on a third-and-19 carry on the game’s opening drive. The rushing attack totaled 7 yards on seven carries the rest of the first half.

Jordan Mason, who entered the week second in the NFL in rushing, managed only five carries for 3 yards in the first half.

TWICE AS NICE FOR HUNT

Kareem Hunt scored two rushing touchdowns for the seventh time in his career — eighth including the playoffs — against the Niners.

After San Francisco broke through with a 55-yard Anders Carlson field goal late in the first quarter, Kansas City took the lead and extended it with 1- and 6-yard touchdowns from Hunt in the second quarter.

Hunt, who rejoined the Chiefs after Isiah Pacheco suffered a broken leg in Week 2, finished with 22 carries for 78 yards and also caught two passes for 5 yards.

He’s now had 63 carries for 249 yards and three touchdowns in three games since returning to Kansas City, which drafted him in the third round of the 2017 NFL Draft.

SHORT-LIVED JUJU

As expected, Kansas City got a pregame boost when wide receiver JuJu Smith-Schuster was active after being limited in practice Thursday and Friday with a hamstring injury.

Mahomes didn’t target Smith-Schuster, who had seven catches for 130 yards in a Week 5 win against New Orleans, before he left the game in the first quarter with a hamstring injury, the Chiefs announced.

Smith-Schuster was the latest Kansas City receiver to go down — joining Hollywood Brown, who got hurt on the first play of the preseason and may be done for the year, and Rashee Rice, who suffered a knee injury Sept. 29 at the Los Angeles Chargers and will miss the rest of the season.

San Francisco had its own receiver attrition to deal with.

Jauan Jennings (hip) was inactive, Deebo Samuel came down ill before the game and played only three snaps and Brandon Aiyuk got knocked out late in the second quarter after being sandwiched between Chamarri Conner and Trent McDuffie on a 15-yard catch.

WAS TAYLOR SWIFT AT THE GAME?

Bruh, you know she wraps up a three-night stint Sunday at Hard Rock Stadium in Miami Gardens, Florida, so don’t pretend like it’s a surprise she was at her day job.

Taylor Swift made it to three of the Chiefs’ first five games — wins against Baltimore, Cincinnati and New Orleans at GEHA Field at Arrowhead Stadium — but she’s back on tour now, including a three-night stop later this week at the Caesars Superdome, which will host Super Bowl LVIX on Feb. 9, 2025.

After that Swift heads to Indianapolis, but it’s possible she’ll travel to Kansas City for its next home game, a Monday Night Football battle against Tampa Bay on Nov. 4, before heading to Canada for six shows in Toronto in late November and three in Vancouver in early December.

Kansas City is 13-3 when Kelce’s insanely famous girlfriend is at the game, including an eight-game win streak dating back to late last season.
