MANKATO (AP) -- A rare occurrence for any NFL team as it begins training camp: no holdouts, no serious injuries.
The Minnesota Vikings are delighted that's them.
"That's kind of a first since I've been here," said owner Red McCombs, who bought the team in 1998.
There are, though, a few missing from the action.
Defensive end Michael Boireau, one of Minnesota's second-round draft picks in 2000, is on the non-football injury list and won't play this season because of a recent relapse of a rare neuromuscular disorder called ocular myasthenia gravis. It causes Boireau's right eye to droop.
"It's a traumatic deal," coach Dennis Green said. "Everybody's got to be patient."
Could Boireau, who missed his rookie season with knee and hand injuries, be in danger of having his career cut short by the condition?
"We hope not," Green said.
Tight end John Davis also is absent from camp, recovering from injuries suffered in a car accident two weeks ago. Green said Davis, who suffered a laceration to his face, might be ready to report by the end of the week. Davis caught 17 passes for 202 yards and a touchdown last year as a backup.
"We're very fortunate it's not more severe," Green said.
Cornerback Carl Kidd and defensive end Lamanzer Williams -- an All-American at Minnesota in 1997 -- are in camp but unable to practice yet. Kidd has a plantar fascia injury to his foot, and Williams is still recovering from offseason knee surgery.
SUNNY SKIES: Monday's practice was hot. Hot and humid. And a little too hot for defensive tackle Fred Robbins and offensive tackle Korey Stringer.
Both had to sit out in the afternoon session because of heat exhaustion.
"It's not unusual for the first day of practice," said trainer Fred Zamberletti, who pointed out the heat index was 109 degrees. "It's ridiculous to think you could condition people in one day."
Especially a guy like Stringer, who is listed at 335 pounds.
"I think Korey does this the first day of every training camp," Zamberletti said with a laugh. "Those big guys carry a lot of weight."
