All players were present and accounted for at Vikings minicamp today, but there was at least one unhappy camper.

Percy Harvin, the Vikings Pro Bowl receiver and kick returner, made it pretty clear that he is unhappy with his contract. Without directly saying so, he said "issues" are involved and unless they are resolved he won't report to the team's training camp in Mankato in late July.

Asked several different times about the contract, Harvin never mentioned that word directly. Harvin has two years left on a five-year deal he got as a rookie in 2009.

"I'm just not happy, I won't go into how unhappy I'm not, I'm just not overall happy with a couple of situations, and hopefully they get worked out," he said.

Coach Leslie Frazier said he had spoken with Harvin. Frazier also wouldn't say what the "issue" was, but added, "It's not something we can't handle. I don't see any reason why he wouldn't be at (training) camp. It's something we will talk through."

Harvin, 24, participated in some of the team's optional workouts during the past month. His rookie contract was worth a little more than $12 million. The final two years of his contract call for base salaries of 915,000 and $1.55 million. With potential bonuses, those two years could be worth slightly more than $2.5 million.

Harvin had 87 catches and 1,312 total offensive yards last season – he was not on the field for about 40 percent of the team's snaps, however.

Jared Allen, who did not participate in the team's Organized Team Activities, said he was happy with his offseason routine and that was why he didn't show up at practice until the minicamp, which is mandatory. There were no OTAs or mini-camps last season because of the NFL lockout, and Allen had a near-record 22 sacks during the season.

Chad Greenway, who missed OTAs because his father has leukemia, was present this morning and spoke optimistically about his father's battle. Greenway said his father's cancer is in remission, but that he was undergoing treatment at Rochester's Mayo Clinic.

Eric Frampton (illness) did not practice.

Middle linebacker Jasper Brinkley was held out of practice with a hip issue connected to the surgery that kept him out of last season. Brinkley said the issue was not a major one and that he expected to take part in practice before the mini-camp ended. Tyrone McKenzie played with the first unit in Brinkley's place.
