Dorsey Sprains Knee in Practice; to Have MRI

The Chiefs have suffered a major injury as first-round pick Glenn Dorsey sprained his knee during practice on Saturday in River Falls.  "It's probably going to be week-to-week," coach Herm Edwards said. "I don't think it's real serious. It's sprained."  Dorsey will have an MRI to determine how bad the sprain is.  He limped off the field and trainers wrapped his knee and put ice on it.  "Whatever time they miss is valuable because they're rookies, as you know," Edwards said. "But the good part is that the other guys are going to have to play and they have to be evaluated."  For now, last years 3rd round pick, Tank Tyler, will take Glenn's place in the lineup.
