Nine-year veteran Erik Pears will get the majority of the reps in Davis' old spot this week during the San Francisco 49ers' three-day minicamp, which is being held inside Levi's Stadium. It won't be Boone, despite being considered the favorite to take that job when the season opens in September.
"Alex, I’m sure at some point will get some work at right tackle," head coach Jim Tomsula said before the start of Tuesday's practice.
Davis, 25, retired Friday, but left open the possibility of a return after a year away from football.
Boone, 28, did not participate in the team's voluntary OTAs this spring and did not get his new playbook until this week. Meanwhile, Pears has been a regular at the team's Santa Clara facility, and his been praised by Tomsula for transforming his body in the weight room since signing in March.
"I really like Pears as a right tackle," Tomsula said. "That’s what he’s played. That’s what we’ve evaluated him most at. I liked the way he was moving.
"He’s bigger and stronger than he’s ever been...But again, we don’t have pads on."
Boone spent the offseason in his typical routine, doing strength training at former Saints center LeCharles Bentley's O-Line Performance facility, in Chandler, Ariz. Pears played right guard for the Bills last season, after playing tackle the previous four years.
This time last year, Boone was holding out for a new contract, which he received after spending the entire offseason away from the team. He signed a two-year, $6 million deal a week before the season-opening win against Dallas, which Joe Looney started in Boone's place. Boone regained his starting status the next week, and got off to a rough start before improving drastically in the second half of the schedule.
Now, Boone is in a contract year, and could make significantly more on the free-agent market should he prove to be a capable tackle. That's where he played during his collegiate days at Ohio State.
The top-five right tackles will make more than half a million dollars in salary than the five highest-paid right guards in 2015, according to Overthecap.com.
"Honestly, the only thing I’m worried about is getting the offense down right now," Boone said Tuesday. "Wherever the coaches want to put me, I’m a team player, I’ll do anything they want. We haven’t really discussed (moving to tackle) that much, so I’ll just leave it up to them."
As far as his first impressions of the new coordinator Geep Chryst's offense are concerned, Boone said, "I’m just excited about a fresh start. Everything looks good so far. You can’t really take anything from minicamp and OTAs, but what we’ve put in so far looks good."
Rookie seventh-round pick Trent Brown is also a candidate to replace Davis.
