Preseason Live Updates: San Francisco 49ers at Kansas City Chiefs

View photos from the 49ers first preseason game against the Kansas City Chiefs.

Football is back. Finally, right? The San Francisco 49ers open the preseason Friday night against the Kansas City Chiefs from Arrowhead Stadium. We're back for another year of live updates to keep you up to speed on all the happenings throughout each game.


While there aren't true "inactives" in the preseason, the 49ers did announce a list of players who won't play on Friday: Jimmie Ward (hamstring, PUP), Dontae Johnson (concussion), Donavin Newsom (concussion), Brock Coyle (rib), Joshua Garnett (knee) and George Kittle (hamstring).

Kittle is expected to go through warmups which is a sign that his hamstring injury isn't serious. The 49ers will be cautious as Kittle could play a big role in 2017.

San Francisco also shared the team captains for Friday night's contest: Joe Staley (offense), NaVorro Bowman (defense) and Aaron Burbridge (special teams).

View behind-the-scenes photos from Arrowhead Stadium as the 49ers prepare for a matchup with the Kansas City Chiefs in Week 1 of the preseason.

First Quarter

The Chiefs started the game on offense and Alex Smith completed a 32-yard deep ball to Tyreek Hill on the first play from scrimmage. A scramble from Smith and a personal foul on Eric Reid helped Kansas City move the ball down the field. Reuben Foster nearly ended the drive with an interception in the end zone, but the ball slipped through his hands.

Kansas City found the end zone on a 2-yard touchdown run from Spencer Ware. (11:38)

The 49ers had two chances to get off the field on third down but failed on both occasions. Rashard Robinson also had a tough drive, allowing the long reception to Hill and missing a tackle on a third down in the red zone. Of note, Lorenzo Foster started at free safety in place of the injured Jimmie Ward. Keith Reaser started in place of Dontae Johnson.

A pre-snap penalty cost the 49ers a third-down conversion and negated a 15-yard pass from Pierre Garçon to Jeremy Kerley. San Francisco went three-and-out instead.

Bad news: It was announced that DeForest Buckner is OUT with an ankle injury. According to Matt Maiocco, he's standing on the sideline and it doesn't appear serious.

Robinson got some redemption. After allowing another long completion, a 30-yard gain to Chris Conley, he came back with a run stop and an interception. Solomon Thomas' pressure forced an errant throw, and Robinson took advantage.

Despite great field position, the 49ers had to settle for a field goal.

Robbie Gould was good from 38-yards out to make it 7-3, Chiefs. (6:11)

Aaron Lynch had himself a nice series. A run stop and pass breakup at the line of scrimmage helped the 49ers defense get off the field. Thomas also got another quarterback pressure.

Brian Hoyer's night is done. He finished 1-for-3 for three yards on two drives. In comes Matt Barkley for the 49ers third series.

A 14-yard completion to Marquise Goodwin was followed by a 63-yard catch-and-run from Aldrick Robinson. Robinson's speed to appears to be underrated as he was able to run away from Chiefs defenders. Of note, Matt Breida got carries before Joe Williams.

Second Quarter

A touchdown pass from Barkley to Robinson was called back due to offsetting penalties. Breida was then stacked up on 3rd-and-goal. Kansas City committed a penalty on the ensuing field-goal attempt to give the 49ers a fresh set of downs. And yet, the 49ers still settled for a field goal.

Nick Rose's 22-yard attempt was good to make it 7-6, Chiefs. (12:22)

Lynch continues to impress. His sack on third down helped the 49ers get off the field once again.

Barkley and Robinson connected again for a 20-yard gain. Joe Williams followed with a pair of 17-yard runs.

Rose drilled a 27-yard field goal to give the 49ers their first lead, 9-7. (6:53)

Barkley is now 4-of-10 passing for 104 yards. Robinson has two catches for 83 yards.

The rebirth of Lynch is real. The linebacker got his second sack of the first half while embarrassing the Chiefs right tackle in the process. This takedown was of Kansas City's prized rookie quarterback Patrick Mahomes.

Trent Taylor has made his preseason debut. Two quick catches for the rookie slot receiver went for 26 yards.

Gould had his 51-yard field goal blocked as time expired in the second quarter. The 49ers will get the ball first in the third quarter leading, 9-7.

Third Quarter

C.J. Beathard started the second half for the 49ers, but went three-and-out on his first drive.

Thomas starred on the following defensive series. He got into the backfield on two straight run plays in short-yardage situations.

Kansas City still managed a field goal to retake the lead, 10-9. (2:58)

San Francisco's next drive ended with a blocked punt. Kansas City recovered at the 49ers 8-yard line.

Mahomes completed a touchdown pass from 1-yard out to Marcus Kemp to make it 17-9, Chiefs. (6:08)

The 49ers offense continues to struggle outside of Joe Williams. Williams has 47 yards on five carries, but San Francisco has allowed three sacks.

Fourth Quarter

Trent Taylor got a rep at punt returner and took it seven yards upfield.

On 3rd-and-11 from the Chiefs 48-yard line, Beathard delievered the play of the day. The rookie avoided pressure in the pocket, stepped up and delivered a strike to Kendrick Bourne for a 48-yard touchdown.

Beathard and Bourne connected one more time on the two-point conversion to tie the game at 17-17. (13:42)

Bourne now has four receptions for 88 yards, a touchdown and a two-point conversion.

Beathard is up to 92 passing yards on five completions.

The 49ers got the ball back when Austin Calitro forced a fumble and D.J. Jones recovered.

Raheem Mostert carried the ball five times for 24 yards to get the ball inside the 5-yard line.

Beathard delivered again, completing a play-action pass to Tyler McCloskey for a 2-yard touchdown to give the 49ers a 24-17 lead. (10:41)

The rookie quarterback now has 94 passing yards and two touchdowns.

Mostert continues to run well and burn the clock. A 19-yard gain got the ball into KC territory with under three minutes to play. Facing 4th-and-1 with 1:00 left, Shanahan opted to kick a field goal to make it a two-score game.

Gould drilled the 33-yarder to make it 27-17, 49ers. (0:56)

Taylor added one more highlight with a 33-yard punt return.

The 49ers topped the Chiefs by that score and improved to 1-0 in the preseason. Now the focus shifts to the Denver Broncos.
