CHIEFS: Smith solid, Mahomes throws first touchdown in loss to 49ers


He's not a fantasy factor while Alex Smith is still starting.

"You can feel good going 4-0 in the preseason, but I've done that before and lost the first game and no one cares what the preseason record was", Shanahan said.

-Defensive end Aaron Lynch, working with the second team, recorded two sacks in the first half.

First, he was beaten badly down the right sideline by wide receiver Tyreek Hill on the game's first play for the 32-yard gain.

San Francisco 49ers head coach Kyle Shanahan looks at the score board during the first half of an NFL preseason football game against the Kansas City Chiefs in Kansas City, Mo., Friday, Aug. 11, 2017. Expect another down year as they are still searching for their quarterback of the future, handing the reins this year to a temporary solution in Brian Hoyer. Barkley finished 10-of-17 for 168 yards. Hoyer did thread a third-and-long pass to Jeremy Kerley, only to have it nullified by one of the 49ers' 17 penalties. The play was called back due to an offensive pass interference call against Conley.

Rookie quarterback C.J. Beathard led a five-play, 23-yard drive following the turnover, finding fullback Tyler McCloskey for a 2-yard touchdown pass to put the 49ers up 24-17. He worked over Chiefs right tackle Jah Reid, a seven-year National Football League veteran. He has been dealing with a hamstring injury. Defensive lineman Ronald Blair went down with a groin injury in the fourth quarter and did not return.

Robinson later badly missed a tackle on a short pass that brought the Chiefs to the 2-yard line, and they scored on an up-the-gut run on the ensuing snap. He finished with 60 yards on seven rushing attempts. In the second quarter, the 49ers had an eight-yard touchdown pass from Matt Barkley to Aldrick Robinson wiped out by penalty.

-Guard Joshua Garnett (knee), cornerback Dontae Johnson (concussion) and linebacker Donavin Newsom (concussion) did not make the trip to Kansas City.

-Jimmie Ward remains on the physically-unable-to-perform list with a hamstring injury.

- The 49ers captains were Bowman (defense), Joe Staley (offense) and, in a positive sign for his roster chances, Burbridge (special teams).
