OTHER BATTLE FRONTS: The competition for the nickel-back position will be intense with Charles Gordon, Marcus McCauley and Benny Sapp all vying for the job. Gordon finished last season in that role but he could be pushed by McCauley. ... The starting linebacker jobs are set with Chad Greenway, E.J. Henderson and Ben Leber returning. But the backup jobs aren't locked down. Free agent addition Derrick Pope would seem a good bet to win a job, in part because he can play on special teams. Heath Farwell and Vinny Ciurciu also have established themselves as top-notch special-teams players. Behind them the battle will include Rufus Alexander, Erin Henderson, David Herron and J. Leman.
ROOKIE REPORT: Second-round S Tyrell Johnson was working with the second team at safety. The Vikings coaches like Johnson's tackling ability and he likely will see plenty of time on special teams. ... Fifth-round QB John David Booty is battling Brooks Bollinger for the No. 3 job. Booty has some experience in the West Coast offense but admits he has plenty to learn. ... Fifth-round DT Letroy Guion will have to fight for a roster spot. The Vikings like his ability but Guion is very raw and might be a guy they try to sneak through to the practice squad. ... Sixth-round C John Sullivan is backing up veteran Matt Birk and also serving as the right guard on the third team. That versatility is extremely valuable and could win him a spot on the game-day roster this season. ... Sixth-round WR Jaymar Johnson made some impressive catches early in camp and also spent time auditioning for a role as a return man. ... Free-agent LB Erin Henderson, brother of Vikings starting middle LB E.J. Henderson, is attempting to win a roster spot at one of the Vikings' deepest positions.
INJURY REPORT: DE Ray Edwards opened camp on the physically-unable-to-perform list and started easing his way back onto the field Wednesday. WR Bobby Wade (knee), TE Garrett Mills (ankle) and DT Kenderick Allen (leg) have also missed time.
DT Pat Williams was held out of 11-on-11 work early in camp as a precaution after having offseason surgery on his left elbow. Williams said he was "day-to-day" and he has been taking part in more drills as camp progresses.
QUOTE TO NOTE: "I'm not good-looking, so they didn't bring me here to be the model of the franchise. They brought me here to produce and produce wins and to work with my teammates to make myself better and make them better. That is my role; my role is to win games." — DE Jared Allen, obtained from Kansas City in an offseason trade for a first-round pick and two third-rounders, on what his role will be with the Vikings.
