Coach Jim Harbaugh, who routinely supports his players on and off the field, made it clear where he stands with 49ers tight end Vernon Davis and guard Alex Boone. “I’m disappointed in that decision for them not to be here,” Harbaugh said Tuesday. Davis and Boone did not report for the opening of the 49ers' mandatory minicamp. Both players are seeking new contracts from the 49ers and have two years remaining on their respective deals. They skipped the first eight weeks of the 49ers’ voluntary offseason program. Davis failed to collect a $200,000 workout bonus, while Boone forfeited his $50,000 workout bonus.
