The Vikings did some more roster shuffling Saturday as the team announced the trade of an undisclosed draft pick to acquire corner back A.J. Jefferson from the Arizona Cardinals. In addition, the Vikings picked up former Bills offensive lineman Mark Asper off waivers, and released offensive tackle Pat Brown and cornerback Zack Bowman to accommodate the new acquisitions.

Rookie wide receiver Greg Childs was scheduled to have surgery Monday to repair the ruptured patellar tendons in both of his knees. He suffered the injury in a freak accident during the Vikings Saturday night preseason practice. Childs told head coach Leslie Frazier that he would be back next year.

The latest indication that Matt Kalil is the most likely selection for the Vikings with the third pick in the draft comes from his older brother and Carolina Panthers lineman Ryan Kalil. He says Matt had a “very good” visit with the Vikings last week, and offensive line coach Jeff Davidson “would really help” his younger brother.

A bit of good news for Vikings safety Mistral Raymond. He won't need surgery on his ankle, but he will miss some time due a bone bruise.
