"Rookie defensive tackle Glenn Dorsey said Sunday that he isn't expecting to return from his left knee injury in time to play in Saturday's preseason game against the Arizona Cardinals.

Dorsey suffered a knee sprain Aug. 2 and returned to practice Saturday, albeit in a limited role. Coach Herm Edwards said Dorsey, the Chiefs' top draft pick, remains day-to-day but did participate in individual and position drills Sunday.

"It never really was a very serious injury," Dorsey said. "I just needed to take some time while it healed."

Dorsey said he expected to return to team practices in the next couple of days. The Chiefs break camp Friday and resume one-a-day practices in Kansas City next week.

"We've got a long time before the opener," Edwards said, "so we don't have to rush this kid. He'll be fine."

Dorsey said he wasn't sure how close to 100 percent he was Sunday, adding that he was "almost there."

Dorsey said there was no pain or swelling in the knee.

"I'm anxious to get back there, but I'm also being smart about it, too," he said. "When I'm 100 percent, I'll go. I've just got to take it day by day and see how it feels.""
