The Kansas City Chiefs had to deal with business much bigger than Sunday's loss -- the health of their head coach. After Kansas City fell to the Los Angeles Chargers, Andy Reid was unable to field questions in his postgame media availability, as the Chiefs announced he was feeling ill. 

NFL Network's James Palmer reported Reid left Arrowhead Stadium in an ambulance and the players were told their head coach should be OK. CBS Sports NFL Insider Jason La Canfora said the move was precautionary. Reid wasn't feeling great and was dehydrated, but there was no serious medical concern regarding the head coach.

"Coach is doing well," the Chiefs said later in the night, "currently resting and in stable condition."

On Monday, Nate Taylor of The Athletic reported that Reid had been released from the hospital and is in good spirits. The Chiefs also expect him to return to work either Monday afternoon or Tuesday morning. 

Tyrann Mathieu posted about Reid after the game on social media, offering the head coach well wishes in his recovery. 

Chiefs special teams coach Dave Toub fielded questions during the postgame press conference in place of Reid, who is one win shy of his 100th victory with the franchise. Reid won 140 games with the Philadelphia Eagles (including the postseason) and 99 with the Chiefs. If Reid reaches 100 wins, he will become the first head coach in NFL history to lead two different franchises to 100 victories. 

The Chiefs play the Eagles next week.
