On Tuesday, the Vikings announced that they have already parted ways with undrafted tackle Mark Jackson.

Jackson came out of Glenville State, after spending some time at Illinois, and received a $3,000 bonus for signing with Minnesota after he wasn’t drafted in April.

The team now has an open roster spot and it is unclear how they plan to fill it.  Some of the top free agents currently available include running back Ahmad Bradshaw, wide out Laurent Robinson, offensive tackle Eric Winston, and guard Brandon Moore on offense.  On defense there are still talents out there like defensive end John Abraham, tackle Richard Seymour, linebackers Daryl Smith and Brian Urlacher, cornerback Will Middleton, and safety Charles Woodson.

More likely, however, is that the Vikings have their eye on another undrafted rookie that they would like to know better.
