Over the last week, the 49ers have seen an influx of key veterans back into the fold.
The latest is right tackle Anthony Davis, who returned to the practice field Tuesday where he participated in individual workouts. It's the first time Davis is working with his teammates after having shoulder surgery in the offseason. San Francisco also got Justin Smith, Ray McDonald and Ian Williams back last week.
Davis revealed in the spring he had the shoulder procedure to repair a "labrum and bicep" injury he suffered in Week 3's loss to the Indianapolis Colts, he told CSN Bay Area. He played through the injury, continuing his streak of 64 consecutive starts to begin his career after being drafted 11th overall in 2010.
In his place, Jonathan Martin has received the bulk of reps with the first team. Martin, despite some struggles during practice, received positive reviews from coach Jim Harbaugh Tuesday.
"Jonathan Martin has done very well. Been a great addition to our football team," Harbaugh said. "Sure glad we got him. Like everybody else on our football team, working to improve in certain areas. He’s been very effective and efficient."
It doesn't look like the 49ers will rush Davis back and play him in the two remaining preseason games. But he is on track to be ready for the regular season opener in Dallas Sept. 7.
The media is no longer allowed to watch full-team practice sessions following the conclusion of "training camp" last week. Wednesday's open practice in Levi's Stadium is the remaining exception. Here are a few notes from the start of Tuesday's practice:
-Patrick Willis, LaMichael James and Mike Purcell were in non-contact blue jerseys at the start of practice. Willis is "working through something" according to Harbaugh. It appears minor. He was in uniform and delivered an impassioned pregame speech prior to Sunday's loss to the Broncos, but did not play.
James returned to practice last week and also appears to be on track to return for the regular season opener, if not sooner. Bruce Ellington has handled the kick and punt return duties in his place, perhaps giving the 49ers more depth at returner than they've had in recent memory. Purcell's injury is unknown.
-Michael Crabtree was away from the team Tuesday after welcoming the birth of his son, Michael Anthony Crabtree III, Monday in his native Texas.
-Antoine Bethea was at practice in street clothes after suffering a concussion Sunday. He's going through the league's standard concussion protocol and will be eased back into the fold as his symptoms subside.
