Vikings bring Jon Cooper up from practice squad

EDEN PRAIRIE, Minn. (AP) -The Minnesota Vikings have swapped backup centers again, waiving Kory Lichtensteiger and signing Jon Cooper from the practice squad.

Cooper made the final cut out of training camp, but was waived the next day when Lichtensteiger was signed after being dropped by the Denver Broncos. The undrafted rookie Cooper was then placed on the practice squad.

John Sullivan is set as the starter. Reserve lineman Ryan Cook can also fill in at center.

Also, the Vikings signed offensive tackle Patrick Brown and wide receiver Vinny Perretta to the practice squad. Wide receiver Nick Moore was released from the eight-person squad.
