Andy Reid, Kansas City Chiefs' coach, has been released from the hospital and will be back at work Monday or Tuesday.
Reid will not be attending his Monday news conference.
Ted Crews, Chiefs' executive vice president for communications, stated that "He is in great spirits and doing well."
According to the team, Reid was taken to Arrowhead Stadium after becoming ill during Sunday's match against the Los Angeles Chargers.
A source said Reid, 63 years old, was being treated for dehydration. He was expected to recover quickly, according to ESPN's Dan Graziano. Although the Chiefs did not specify what was wrong with Reid in Sunday's statement, they said that Reid felt "ill" but that the team had stated that Reid is currently in stable condition and "doing well."
He was able to stay on the sidelines until the Chiefs' loss of 30-24 and then returned to the locker area.
Reid addressed the team the same way he would normally after a game. At least one player, Clyde Edwards Helaire, stated that he didn't know anything unusual.
The team stated that Reid was feeling sick and left for the University of Kansas Health System to receive further evaluation. Reid did not address the media like he normally would after a game. This job was taken over by Dave Toub, assistant head coach.
