Kansas City, Mo. ? There will be no fear of that first hit, Trent Green says.

Ten weeks after he was knocked unconscious with a severe concussion, the two-time Pro Bowler is just happy to finally be back as the starting quarterback for the Kansas City Chiefs.

Given medical clearance by an array of doctors after a battery of tests, Green will start Sunday against Oakland. It will be his first live action since Sept. 10, when Cincinnati’s Robert Geathers came flying in and hit him with a shoulder, snapping his head violently to the turf.

The ambulance was almost at the hospital before he regained consciousness. For a couple of weeks, he wasn’t even able to drive. Only earlier this month was he allowed him to begin even limited practice.

“I don’t anticipate having (fear) on Sunday,” Green said Thursday. “Just because of some of the things I’ve been through early in my career. No, you can’t play the position with fear, and I don’t anticipate doing that.”

Nevertheless, about 79,000 fans in Arrowhead Stadium are going to hold their collective breath the first time some Raiders defender like tackle Warren Sapp or linebacker Kirk Morrison gives their 36-year-old quarterback a good pop.

“You’ll just say, ‘I’m glad it’s over,”‘ said coach Herm Edwards. “I think once he gets the snap from center and he goes back and it’s a pass and he sets up in the pocket, if he gets knocked down, you’ll go, ‘OK, that’s done. Let’s go.”‘

Before getting medical clearance to resume the physical sport of football, Edwards said, Green underwent “more tests than the astronauts.”

“He’s probably waiting for (that first hit),” Edwards said. “He might go out there and hit somebody himself, just to get it over with.”

While Green was out, backup Damon Huard performed much better than just about anybody expected, going 5-3 as a starter and throwing only one interception while hitting 11 touchdown passes. While he waited impatiently to get the doctors’ OK and watched Huard do well, Green admits he flashed back more than once to 1999.

That’s when he suffered a devastating knee injury in the preseason and lost his starting job with the Rams to Kurt Warner. By the time he was healthy again, Warner had led the Rams to the Super Bowl and been voted the league MVP.

Was he concerned about losing his job again?

“There’s always concern, especially since it’s happened to me before,” he said with a grin. “So there’s always concern, but I have confidence in what I do. I had confidence in myself in ’99 that when I came back and had an opportunity to play, that I’d play well. It was nothing against Kurt. He played great, and obviously was the league MVP. But it didn’t make me think any less of myself and I think that’s something you have to have.”

As far as the Raiders go, Morrison said it doesn’t matter whether Green or Huard gets the start.

“It doesn’t change anything at all. They’re a great offense with either one of those guys,” he said. “No matter who plays quarterback they have the ability to score a lot of points.”
