Vikings' Loadholt to have MRI on Sunday

KANSAS CITY -- Minnesota Vikings right tackle Phil Loadholt, who briefly left Saturday's game against the Kansas City Chiefs with a lower leg injury, will have a MRI on Sunday, but coach Mike Zimmer said team doctors don't see cause for great concern.

"They don't believe it's anything real serious," Zimmer said.

Having Loadholt healthy going into the regular season would be of great importance to the Vikings, who are going into their third season with the same five starters on the line and made Loadholt one of the highest-paid right tackles in the game last year. Undrafted free agent Austin Wentworth was beaten on a blitz after replacing Loadholt on Saturday night, and Jaye Howard knocked the ball away from Matt Cassel for a safety, in a moment oddly reminiscent of what happened to veteran tackle J'Marcus Webb last November after he replaced an injured Loadholt in Dallas and allowed an end zone strip-sack that the Cowboys recoveed for a touchdown. The Vikings also count on Loadholt as a key piece of their running game, and the 6-foot-8 tackle's force at the point of attack would be tough to replace.

Safety Jamarca Sanford sustained a quadriceps injury on a special-teams play early in the game, costing him an important chance to earn playing time at safety and keep himself in the race for a starting spot there. "It's hard to evaluate him when he's sitting on the sideline," Zimmer said.

Sanford, who has dealt with injuries since the Vikings' offseason program, wouldn't go into much detail about his latest ailment, other than to say, "I'm good. I don't know how I'm feeling right now. I'm upset, frustrated, just with not being able to go, because you get hurt. It's part of the game."
