Tight end Vernon Davis' apparent contract dispute could lead to him 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 while appearing 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.

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