Chiefs coach Andy Reid went to the hospital via ambulance after last week's loss to the Chargers as an extreme precaution, but quickly felt better and had no setbacks this week. There are no concerns about any other health issues arising, league sources said, in what looks like an isolated issue due largely to dehydration.

Reid, 63, coached the game as normal and addressed the team before returning to his office to shower and go home. He felt a little uneasy and unusual at that point in time, the sources said, and after conferring with team doctors they believed it was best to have Reid checked out to rule out anything significant. With the stadium parking lots still backed up, going by ambulance was the easiest way to transport him. Reid was monitored at the hospital and did not require any substantial treatment and then returned to the team for a normal work week.

"No reason for concern, whatsoever," said one source with knowledge of the situation. "Andy is doing great. It was an isolated thing."

Reid's health has been a concern in the past but he just committed to a new six-year deal a year ago, after the Chiefs essentially tore up his existing deal after winning the franchise's first Super Bowl. He has a chance to join the top three in all-time victories by a head coach and, associates said, feels refreshed and invigorated by quarterback Patrick Mahomes and this team, which is an annual Super Bowl contender.

"He isn't going anywhere anytime soon," said one confidant. "He wants to keep winning with this kid (Mahomes) for a long time, Why do you think he did a six-year deal? And the quarterback did a 10-year deal. This isn't going away."
