SANTA CLARA -- Running back Matt Breida, who is tied for the NFL’s rushing lead, is listed as questionable for the 49ers’ Week 4 game at the Los Angeles Chargers, head coach Kyle Shanahan said Monday.

Breida sustained a hyperextended right knee Sunday during the first half of the 49ers’ 38-27 loss to the Kansas City Chiefs. He returned in the third quarter and finished with 90 yards on 10 carries. Breida on Monday also had some calf soreness, Shanahan said.

Shanahan made note of the playing surface at Arrowhead Stadium, which recently had been re-sodded after a Sept. 8 Taylor Swift concert. He said he wasn't sure if the turf had anything to do with the injuries to Breida or quarterback Jimmy Garoppolo, who tore the ACL in his left knee when he tried to make a cut near the left sideline to stay inbounds.

Entering the Monday night game, Breida is tied for the NFL lead with Dallas’ Ezekiel Elliott with 274 rushing yards on the season. Breida has carried the ball 32 times this season and is averaging 8.6 yards per attempt. Elliott has attempted 48 runs.

Shanahan gave other 49ers injury updates Monday:

-- Cornerback Richard Sherman has a calf strain and is expected to miss a couple of weeks.

-- Guard Mike Person has a knee sprain and is questionable for the game against the Chargers.

-- Guard Joshua Garnett still is nursing a toe injury and isn't expected to be available.

-- Wide receiver Marquise Goodwin made it through Sunday’s game healthy after sitting out Week 2 with a deep thigh bruise.

-- Safety Adrian Colbert sustained a hip injury and will be re-evaluated Wednesday.

-- Running back Alfred Morris had an ankle injury but returned to action. His practice availability will be determined Wednesday.
