SANTA CLARA -- It's unknown how long it will take Alex Boone to seize the 49ers' starting right guard position after missing the team's entire preseason. But he'll arrive at team headquarters today in very good shape, said the man who trained with him in Cleveland.
There wasn't a whole lot to do throughout the course of a day, noted LeCharles Bentley, who runs a training facility for offensive linemen. So he spent a lot of time with me.
Bentley, a former NFL offensive lineman who has known Boone since the latter was in high school, said Boone worked out six days a week and that the sessions were anywhere from an hour to double sessions that took up nearly half the day.
Boone will have to pass a physical when he arrives. Then the 49ers coaches will determine how long it will take him to be ready to play in a game, something Boone has not done since Jan. 19. Neither has the man who played next to him the last two years, right tackle Anthony Davis.
Davis had shoulder surgery in April and also missed the entire offseason program. Asked whether Davis would be ready for Sunday's season opener in Dallas, Jim Harbaugh on Saturday said, We'll see.
That means there's a chance that the starters for the game could be the same as they were throughout the preseason Joe Looney at right guard and Jonathan Martin at right tackle. Also up in the air at the moment is reserve lineman Dillon Farrell's role on the team.
He can play all five spots on the offensive line, making him an ideal emergency offensive lineman. But the 49ers also may need his roster spot if Boone's roster exemption goes away when his holdout ends.
Another possibility: Boone takes injured nose tackle Glenn Dorsey's roster spot. That spot, however, won't be available until Tuesday when Dorsey is first eligible to go on the injured reserve/designated to return list.
