Speaking with Kansas City reporters for the first time since the head-snapping hit in the season opener, the two-time Pro Bowler said Thursday that he's feeling much better and finally able to drive a car. He may even join the Chiefs on the sideline Sunday for their game against San Francisco.

``It's just a day-to-day, week-to-week thing. That is what the doctor told me my last visit last week, to not expect anything other than that,'' he said.

``Everybody handles it differently. Every concussion is different.''

Getting back by Oct. 8 against Arizona, he said, would not ``be reasonable.''

``They're going to want me to practise at least some prior to that point. I know I won't practise this week. It remains to be seen if I'm going to do any next week. So considering by that point in time I will have missed three weeks, to all of a sudden practise and play in one week, that would be reaching.''
