49ers injury report: Anthony Davis, Glenn Dorsey ruled out

Anthony Davis, who started the first 64 games of his NFL career but has already missed five games this season, will miss a sixth game on Sunday.

The San Francisco 49ers’ fifth-year right tackle, who has already battled shoulder, hamstring and knee and ankle issues this season, was ruled out of the team’s game against Washington still suffering from symptoms of the concussion he suffered late in the Niners’ victory at the New York Giants on Sunday.

With Davis out, Jonathan Martin will start at right tackle for the sixth time this season.

“Yes, feel good about Jonathan Martin,” said coach Jim Harbaugh.

Also ruled out was nose tackle Glenn Dorsey, who was just added to the 53-man roster from the short-term IR on Monday. Dorsey suffered a torn left biceps tendon in training camp but is listed as having a forearm issue now.

With Dorsey out and Ian Williams on injured reserve, Quinton Dial figures to start at nose tackle for the second straight week.

And while both cornerback Tramaine Brock and receiver/kick returner Bruce Ellington were listed as questionable to play, neither practiced this week.
