SANTA CLARA -- The 49ers have received inquiries from teams regarding the availability of holdout guard Alex Boone but are not interested in dealing him, a source told CSNBayArea.com.
Another source said the 49ers have told teams that they would be willing to part with Boone for a first- or second-round draft pick -- a price that is considered exorbitant for an offensive guard.
Boone, who is under contract for two more seasons, has skipped the first four weeks of training camp and is subject to fines of $30,000 daily.
He also sat out the team's offseason program, including a mandatory minicamp.
The 49ers made Boone a contract offer that added new years to his existing deal that is scheduled to pay $2 million this season and $1.2 million in 2015.

NFL.com reported this week that the 49ers offered Boone a deal that would pay him among the top-12 of guards.
But a source said if that were the case, Boone would already be signed and under contract. That money in the 49ers' proposal would not kick in until the 2016 season, sources said.
Guard Joe Looney has been starting at right guard in Boone's absence. Boone does not plan to report to the 49ers without a new contract.
"We believe in Joe Looney," 49ers coach Jim Harbaugh said. "We believe we can win with Joe Looney. Again, Joe Looney is working every day to improve his game and that’s what the unit is doing, all 11 and key backups."
