MANKATO -- Vikings running back Adrian Peterson remains optimistic that his charge of resisting arrest will be dismissed before he's required to face the charge in court in Houston on Aug. 6.

He also seems unconcerned about the whole situation, describing his handling of it as "pretty laid back, to be honest."

"I haven't lost any sleep or anything over it," he continued during a press conference reporters outside Gage Hall at Mankato State. "I know in due time things will get handled and justice will be served. It was an unfortunate situation. I feel like everything will get worked out."

Asked what his confidence level is that he'll be exonerated, he referred to a comment he made earlier this month.

"To repeat, 200 percent," Peterson said. "I'm confident. Wrong is wrong and right is right. I did nothing wrong in this situation and ultimately that will be shown."

Asked if he was worried about his surgically rebuilt left knee during the scuffle with police, Peterson said, "No. My knee was the last thing I was worried about. I was worried about my face."

Vikings coach Leslie Frazier said the team will deal with Peterson's legal situation if he has to miss practice to return to Houston. Frazier also said he was going to talk to Peterson later today about whether Peterson will start training camp on the physically-unable-to-perform (PUP) list, which is expected.

"To be honest, I'll try to fight against" being put on PUP, Peterson said.

Either way, Frazier said Peterson will be on the field on Friday. If he's on PUP, he'll be working out off to the side.

Frazier said every other player on the roster has been cleared medically to practice.
