KANSAS CITY, Mo. -- Kansas City Chiefs coach Andy Reid left Arrowhead Stadium and was transported to a local hospital system after feeling ill following Sunday's game against the Los Angeles Chargers, according to the team.
Reid, 63, was treated for dehydration and he is expected to be fine, a source told ESPN's Dan Graziano. The Chiefs didn't specify in a statement on Sunday night what was wrong with Reid, only saying that he "felt ill," but the team did say the coach is "doing well, currently resting & in stable condition."
Reid stayed on the sideline until the end of the Chiefs' 30-24 loss and returned to the locker room afterward.
Reid addressed the team as he normally would after the game, and at least one player, running back Clyde Edwards-Helaire, said he was unaware there was anything out of the ordinary.
But Reid felt ill and departed for The University of Kansas Health System for further evaluation, the team said. Reid didn't address the media as he would normally after a game, leaving that job for assistant head coach Dave Toub.
A source close to Reid told ESPN's Jeff Darlington that the coach was in good spirits when he departed for precautionary observation after he felt ill.
Reid left in an ambulance less than an hour after the game ended, a source told Darlington.
Safety Tyrann Mathieu tweeted about Reid after the game, saying, "I'm praying for my Head Coach & I'm hoping you can send up prayers with me!! One of the best men & teachers I've been around!!! GOD please show us your mercy!"
