SANTA CLARA – Right tackle Anthony Davis, who underwent offseason shoulder surgery, made his return to the 49ers’ practice field on Tuesday.
Davis, who was not wearing pads, took part in individual drills before practice. Davis was not involved in team drills and does not figure to play in the 49ers’ exhibition game Sunday against the San Diego Chargers at Levi’s Staidum.
But Davis is expected to be on the field for the regular-season opener on Sept. 7 at the Dallas Cowboys. Davis has not missed a start in his four-year NFL career.
Veteran Jonathan Martin has filled in at right tackle during Davis’ absence. Martin missed time during the offseason program with mononucleosis.
His strength was an issue during the first three weeks of training camp. But Martin’s play looked noticeably better last week, including his performance in a shortened stint Sunday against the Denver Broncos.
“Jonathan Martin has done very well,” 49ers coach Jim Harbaugh said. “Been a great addition to our football team. And were glad we got him. Also, like everybody else on the football team, (he’s) working to improve in certain areas, but he has been very effective and efficient in his play.”
