Chiefs' Holmes goes through first full practice of comeback

Edwards said Holmes went through a full practice, even working some on the scout team against the first-team defense.

"He still has quickness," he said. "He has burst. He has great acceleration. He hasn't lost that. Maybe he doesn't have what he had four years ago, but he's still OK. He didn't get hit and lay down and not want to come back. He got up and dusted himself off and got back in the huddle and did it again.

"Now, I've got to see tomorrow what happens."

Throughout his career, Holmes has confounded those who counted him out. A knee injury in college kept him from being drafted, but he signed with Baltimore and became a 1,000-yard rusher. The Ravens let him go in 2000 and he immediately became a Pro Bowler with Kansas City.

Many thought a hip injury would end his career in 2002. But the next year he set an NFL touchdown record.

"If you put your mind to anything, no matter what it is, with training, you can accomplish any goal in life," he said. "I believe that."

He said he doesn't feel he has anything to prove.

"I think the proof came when I was able to go through camp. That's where doubt could come in and say, 'You're crazy for coming back. Why do you even want to get up at 7 o'clock in the morning? You could be back in Texas. You could be on your jet skis and on your motorcycle.'

"But there's a time and place for everything. And I believe that this particular time is an opportunity for me to come back to the league."
