Vikings camp Day 2: Storms roll in

MANKATO, Minn. -- Some thoughts and observations after one of the wackiest weather days I've ever seen at an NFL training camp:

  • The Vikings had to work awfully, awfully hard to push through their final full-pads practice of camp. It was originally scheduled to start at 10 a.m. ET, but lightning forced them off the outdoor fields at Minnesota State University, Mankato. Coach Brad Childress then flipped his intended schedule, devoting the rest of the morning session to an indoors special teams practice and then restarting the full-pads practice at 3:45 p.m. ET. Clouds rolled in about midway through that session, darkening the skies to near-night conditions, before passing over. Between the two sessions, the Vikings got about two hours' worth of full-pads practice in.

  • Tailback Adrian Peterson participated in a "live" tackling drill for the first time in camp. He had been limited by a strained hamstring and pulled up late in the practice after a run down the sideline. It's not clear if Peterson was re-injured, but he did not return to practice.

  • Middle linebacker E.J. Henderson, working to make his way back from a fractured femur, made a nice stop of Peterson at the line of scrimmage during a short-yardage drill.

  • Quiz time: Who is the Vikings' backup long snapper? Check the end of this post for the answer.

  • Kickoff specialist Rhys Lloyd handled field goals during the early portion of practice, converting five of six attempts, including a long of 50 yards. To respond to a number of questions on this topic, I have no evidence of a place-kicking competition here. Lloyd isn't going to beat out Ryan Longwell when it comes to field goals. He is here for kickoffs only.

  • The Vikings released an unofficial depth chart before practice. It listed Asher Allen as the starting right cornerback. But during team drills Tuesday, Lito Sheppard worked as the right cornerback with the first team.

  • Defensive end Jared Allen handled long snapping Tuesday while Cullen Loeffler attended to a family issue. Allen was drafted primarily as a long-snapper out of Idaho in 2004.
