Peterson said the sore hamstring that landed him on the injury report last week for the first time this season has been bothering him for about five weeks.
"I feel like I can keep playing through it. I'll be OK. It's not tweaked or anything. It actually came from a bruise that occurred about five weeks ago," Peterson said. "I think just over-working the hamstring brought that tightness. So now I'm like, my hamstring is tight. I don't want to stretch or pull anything so it's more that type of situation."
Still, Peterson isn't looking to have his carries reduced. Last year, the Vikings were cautious with Peterson's carries early in the season coming off knee surgery in December 2011. This year, they proclaimed, there was no pitch count for him.
But with an ailing hamstring, he has carried only 23 times in the last two games.
"Any time you have two games with 13 carries or less, you definitely want more touches to get in the flow of things," Peterson said. "(Carolina), the game got out of whack so we had to get away from the run game. But one thing that we're going to do and get back to focusing on is establishing the run, getting those guys up front working and sweating and then be able to become more balanced."
Against Carolina, a 35-10 loss in which Peterson had 10 carries, the score got away from the Vikings and they had to become more one-dimensional. But after Monday night's game against the New York Giants, head coach Leslie Frazier said the lack of carries had nothing to do with the score.
Peterson joked that the ideal number of carries for him in a game is 100, but he said he didn't think he had to have a conversation with the coaches about his declining carries.
He also said he didn't tell the coaches about his hamstring tightness until last week.
"That's when I really felt, OK, I'm starting to feel something now that could slow me down a little bit," Peterson said. "I really didn't say anything to those guys until like last week. Just told them there's tightness. It's more so when I run. I was kind of hesitant to stretch out and really stretch the hamstring, thinking that I was going to pull (it). So that's how I kind of had it in my mind. But that had nothing to do with the coaches' decisions."
FREEMAN LIKELY INACTIVE
Josh Freeman still isn't practicing, although he was watching practice Thursday after suffering concussion-like symptoms following the loss to the New York Giants on Monday night.
That said, Frazier said it's unlikely Freeman would be active Sunday night against the Green Bay Packers, saying they wouldn't want to put him out there with little practice this week.
RB Matt Asiata (shoulder), TE Rhett Ellison (ankle) and WR Rodney Smith (hip) didn't practice Thursday.
LB Chad Greenway (wrist), CB A.J. Jefferson (ankle), K Blair Walsh (hamstring) were limited for the second straight day. DT Sharrif Floyd (back) was added to the injury report Thursday as limited.
Frazier said Greenway should be fine. "Nothing that should inhibit him," he said.
