MANKATO, Minn. -- Some thoughts and observations from the final Minnesota Vikings practice of CampTour'12:
On one of the final plays of the night, rookie receiver Greg Childs suffered an injury significant enough to leave him screaming in pain. Coach Leslie Frazier didn't have any immediate information on its severity or nature, but it happened about 10 feet in front of me as I watched practice from the end zone. Childs jumped to catch a ball thrown slightly behind him. It bounced away, and Childs landed awkwardly. He initially clutched his right leg, but a team of medical officials were also examining his left leg. Eventually, four men lifted him, his legs fully extended, onto a cart.
Frazier did confirm that offensive lineman Geoff Schwartz will undergo surgery for a sports hernia and will miss at least a month. That in essence makes Brandon Fusco the Vikings' unquestioned right guard.
During an extended special teams period, rookie place-kicker Blair Walsh converted seven of eight attempts, including one from 50 yards. Based on unofficial practice tracking from Tom Pelissero of 1500ESPN.com, Walsh has now converted 24 of 26 field goals during team drills in training camp.
Quarterback Christian Ponder hit receiver Percy Harvin on a slant for a touchdown in an early team drill, but afterwards he was lamenting an overthrow on a deep post route to receiver Jerome Simpson. "At this level," Ponder said, "you can't miss those."
Rookie cornerback Josh Robinson got his first extensive action since injuring a hamstring early in camp. Robinson showed up on several plays, including a tip-away of an earlier pass intended for Childs.
