According to Judd Zulgad of the Minneapolis Star-Tribune, via Twitter, the Vikings have officially signed former Eagles, Dolphins, and Hartford Colonials running back Lorenzo Booker. In order to make this move, they have placed running back Albert Young on waivers.
In another move, the Vikings have signed QB R.J. Archer to the practice squad, waiving center Adrian Martinez to do so.
Not sure if the Vikings are going to attempt to bring Young back or not, but if not, we wish him the best in his future endeavors.
EDIT: Young is now saying via his Twitter account that he was placed on injured reserve, not waived by the team.
We apologize to Mr. Young for the error if that's the case.
