49ers notes: Anthony Davis plays guard for first time in nine years

Anthony Davis started Friday’s contest at right guard, his first in-game snaps at that position since he was a freshman at Rutgers.

Davis, the 49ers’ starting right tackle from 2010 to 2014, sat out last season because of health concerns. When he rejoined the team this summer, his right-tackle spot had been taken by Trent Brown.

Davis said he volunteered to play guard because he knew he had the athleticism to make the move.

“I’m an athlete,” Davis said last week. “I can play right tackle. I can play anywhere along the line. We want the best five (linemen) on the field, and Trent is not going to play guard. He’s a giant man. And I feel like I could adapt to guard.”

Zane Beadles started the game at left guard, but first-round pick Joshua Garnett replaced him on the third series. Other starters Friday included Ray-Ray Armstrong at inside linebacker and first-round draft pick DeForest Buckner at defensive end.

Kap’s visor – Colin Kaepernick played in Friday’s game with a clear visor instead of the tinted one he’s been wearing since the offseason. Clear visors are permissible, but tinted ones require NFL approval, which Kaepernick has not yet received. Players risk a fine if they wear a tinted visor without approval.

According to a source close to Kaepernick, he asked the league for permission to wear the visor on July 28 but only heard back in the run-up to the Packers game. A league spokesman said an independent ophthalmologist must verify that the visor is necessary before the NFL grants approval.

In June, Kaepernick said the visor was needed to protect his eyes.

“Been doing a lot of things to make sure my vision’s correct,” he said. “So the visor’s been there to help with that.”

Armstead sits – Arik Armstead (shoulder) was one of several 49ers who didn’t suit up for the game. Armstead hurt his left shoulder during a practice on Aug. 7 and has missed every preseason game so far.

The team has downplayed the injury, although it’s possible that Armstead won’t play at all in the preseason. The 49ers’ preseason finale is Thursday in San Diego.

Chip Kelly hinted during the week that Armstead might not play.

“We’ll always err on the side of caution from that standpoint because you do want to win every preseason game,” he said. “You want to be successful in everything you do, but you really don’t get a whole heck of a lot if, you know, ‘Hey, we were 4-0 in preseason and killed everybody.’ 

Et cetera – Defensive lineman Quinton Dial (knee) and receiver Bruce Ellington (hamstring) left the game and did not return. Safety Eric Reid briefly left the game with a thumb injury.
