Future Pro Football Hall of Famer Adrian Peterson was released by the Tennessee Titans just over a week ago, but it didn't take him long to find a new opportunity. On Wednesday, the running back signed on with the Seattle Seahawks practice squad, as Pete Carroll wanted to add another running back to the fold since his ground game has been lacking.

The Seahawks aren't the only team that has been poking around the running back market as of late, as Peterson's former team in the Minnesota Vikings has been as well. Dalvin Cook was carted off the field last week during the Vikings' loss to the San Francisco 49ers, and an MRI reportedly revealed that he suffered a torn labrum. However, head coach Mike Zimmer told reporters that Cook didn't tear his labrum, and would instead be day-to-day

Even though it appears Cook is going to play through the injury, Minnesota reportedly worked out running back Kerryon Johnson. This upset Peterson's father, that Minnesota did not reach out to its franchise legend for a reunion. 

"That's disappointing to me. He never heard anything from the Vikings and you go in and bring in a guy Adrian beat out in Detroit (in 2020)," Nelson Peterson said, via Chris Tomasson of the St. Paul Pioneer Press. 

Peterson was open to inquiries when Minnesota decided to work out Johnson. Before being cut loose, Peterson played in three games for the Titans and rushed 27 times for 82 yards and one touchdown. He is currently fifth on the all-time rushing list with 14,902 yards, and owns several Vikings franchise records such as most career rushing touchdowns (97) and most career rushing yards (11,747).

It sounds as though the Vikings aren't looking for a full-time replacement since Cook will try to play through the injury. It could be viewed as a slight to a Viking legend if Minnesota brought in Peterson only to potentially cut ties with him a couple weeks later. Still, Nelson Peterson thinks it's silly that his son didn't get a call.
