After not being picked in the 2011 NFL Supplemental Draft, former Georgia running back Caleb King became a free agent. Like all undrafted free agents, he was free to sign with any NFL team, and per Marc Weiszer of DogBytes Online, King has agreed to a deal with the Minnesota Vikings.
The former Georgia running back went unselected in this afternoon’s NFL supplemental draft, but has agreed to a free agent deal with the Minnesota Vikings, according to his agent Kevin Conner.
He said that King had "multiple offers," and took his time before making the decision.
It's not clear if the Lions were one of the teams that offered King a deal. I tend to believe they were considering they are dealing with so many injuries at the running back position and showed interest in him before the Supplemental Draft, but it's a moot point now with King headed to the division rival Vikings.
The other players not picked in the Supplemental Draft -- defensive end Keenan Mace (Lindenwood), defensive end Mike McAdoo (North Carolina), defensive back Torez Jones (Western Carolina) and defensive back Tracy Wilson (Northern Illinois) -- are still unsigned as far as I know.
