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.

Christian Ponder is probably feeling a littler safer today because the Vikings are expected to sign free-agent offensive lineman Geoff Schwartz. Schwartz broke the news on his Twitter page by tweeting he's "excited to be a Minnesota Viking." The 6-foot-6, 331 pound lineman is projected to replace Anthony Herrera at right guard.

Vikings guard Geoff Schwartz joins a growing list of injured players at training camp in Mankato. He has been sidelined with abdominal strain and was sent back to the Twin Cities for further evaluation. Vikings head coach Leslie Frazier says the former Carolina Panther was having difficulty turning his body.

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.
