That's the latest from NFL Media Insider Ian Rapoport, who said as much on Sunday night's NFL Total Access.
The 30-year-old running back will play for the Vikings or no one, or at least that is the word coming from Minnesota, per Rapoport.
A deal for Peterson would likely happen on Friday or not at all. Any return on the All-Pro would expected to yield a second-round pick and if the Cardinals do not find a running back they're in love with on Thursday night, Peterson could be the guy in Round 2.
Still, this will make for a fascinating subplot to the second day of the draft.
As we continue to obsess over the landing spots of two quarterbacks, a trade for Peterson could actually have the most immediate impact around the league. Pairing Carson Palmer, Larry Fitzgerald and Michael Floyd with the NFL's most dominant running back would automatically make them one of the favorites to win the conference along with their division mates, the Seattle Seahawks.
