SANTA CLARA -- Tight end Vernon Davis' apparent contract dispute could lead to his missing next month's mandatory minicamp.

Davis did not participate in the 49ers' first week of organized team activities, and he would not commit Friday to attending a June 17-19 minicamp that would result in nearly a $70,000 fine if he skips it.

"I'm not sure. I'll talk to my agent," Davis told the Sacramento Bee at a Jamba Juice store he owns in Santa Clara.

Davis has base salaries of $4.7 million and $4.35 million for the final two seasons of a five-year extension he signed in 2010.

In October, San Francisco-based Fantex bought a 10 percent stake in Davis' future earnings for $4 million.

Last season, Davis earned the second Pro Bowl invitation of his eight-year career. He matched a career-high while catching 13 of Colin Kaepernick's 21 touchdown passes in the regular season.

Davis had five receptions in the three playoff games, but he produced touchdown catches in wins at Green Bay and Carolina.

Right guard Alex Boone also missed this week's OTA sessions while also reportedly seeking a new contract with two years remaining on his deal.

Kaepernick, wideout Michael Crabtree, running back Frank Gore and guard Mike Iupati are among the players entering the final season of their contracts.

"I don't know which one is a priority. There are a lot of guys we'd like to extend," CEO Jed York said. "There are a lot of things we're working on. We obviously can't get everything done."

York, speaking on the 49ers flagship radio station KNBR 680, also addressed the negative publicity surrounding the team. At least five players have been involved in police investigations the past four months, as well as nine arrests since 2012.

Stating that off-field issues occur on a "normal basis," York said he believes the 49ers have done a "pretty good" job in working with players to overcome them.

"We have to make the decision: Do you put up with some of those issues or you don't?" York said. "I don't think we try to sign guys that are going to get into trouble."

York spoke only generally about recent cases involving linebacker Aldon Smith, Kaepernick, wideout Quinton Patton, cornerback Chris Culliver and center Daniel Kilgore.

York attempted to defuse talk of friction between coach Jim Harbaugh and general manager Trent Baalke, stating they've "always had a good working relationship" with their recently heralded draft class being an example of that.
