Peterson reported to training camp Thursday with the rest of his Vikings teammates at Minnesota State University, with the first practice set for Friday. The Vikings still were in the process of determining how much activity they'll immediately allow Peterson, who's seven months out from reconstructive surgery on his left knee to repair torn anterior cruciate and medial collateral ligaments.
"He'll at least be out there doing something," Frazier said.
He could, however, be placed on the physically unable to perform list. There's no downside for the Vikings in doing that, since Peterson can be taken off at any time during camp. The hard part would be keeping Peterson happy.
"I'm going to try to fight against it so I can get out there and be involved," Peterson said. "But ultimately I know these guys are going to do what's best for this team."
Which includes being cautious with their franchise player ahead of the Sept. 9 season opener, for which Peterson has steadfastly maintained he'll be ready.
"It feels good just to be around the guys and be around everyone who has supported me through this process, and even more importantly, it's going to feel good to be able to participate and do some things with the guys," Peterson said. "So I'm just excited to be here. I'm excited to get things going."
First-round draft pick Matt Kalil signed in the morning, completing the contracts for the rookie class and ensuring the entire roster's on-time arrival. Wide receiver Percy Harvin, who stirred up an otherwise-quiet minicamp last month with his vague expression of discontent and subsequent trade request, didn't speak to reporters but arrived with a smile on his face as he raced around trying to find his rental bike and get to the first team meeting.
"Everybody seems to be in the right frame of mind, including Percy," said Frazier, who wore a max-relax outfit of lavender golf shirt, white cargo shorts, sandals and ball cap. "It's exciting."
