EDEN PRAIRIE (AP) -- The Minnesota Vikings not only are looking for a few more interceptions, they might need a cornerback, too.
Cris Dishman could miss Sunday's game against Arizona because of a mild shoulder separation. Last week, the Vikings lost free safety Orlando Thomas for 8-10 weeks because of a broken shoulder.
Suddenly, the Vikings could be without half of a secondary that has produced an NFL-low three interceptions. Dishman and Thomas each had one of them. Without the two, the Vikings will start a secondary that hasn't intercepted a pass.
Kenny Wright, who plays on passing downs, will start if Dishman is unavailable. Rookie Tyrone Carter is starting in place of Thomas.
"The injury situation that affects most teams is starting to play itself out with us," coach Dennis Green said.
Besides an assortment of injuries to second-team players, Green also revealed that quarterback Daunte Culpepper is limited by a sore tailbone and knee.
"He's not running quite a 4.4," Green said.
That could explain Culpepper's struggles in losses the past two weeks, though some of that probably was inevitable in the sophomore's first full season as a starter. Culpepper has thrown five interceptions the past two games, after being intercepted only three times in his previous five games. He also has run with the football only four times in each of the past two games, matching his fewest carries of the season. If his ability to run with the football is limited, that's an important option taken away from him.
"I still can run," Culpepper said. "I still feel good. I'm probably 90 to 95 percent. In the heat of battle, you don't think about that. I don't."
The Vikings, who were nearly injury-free over the first half of the season, also are likely to be without special-teams player Craig Sauer because of a leg injury. Backup defensive lineman Roy Barker might not play because of a groin injury, but defensive end John Burrough is expected to return after missing two games because of an ankle injury.
Dishman, who ran on a treadmill Wednesday rather than practice with the team, continued to play in the 26-20 loss on Monday night to the Green Bay Packers though his shoulder was separated in the third quarter.
He refused to say whether the injury hampered his shot at intercepting the pass that wound up first on the shoulder and then in the hands of the Packers' Antonio Freeman for the improbable winning touchdown.
"Green Bay is over," Dishman said. "It's time to concentrate on Arizona. My main goal is getting my shoulder right."
