Bowles spent Friday in the hospital before traveling to New England to rejoin the Jets at the team hotel on Saturday morning. He later coached from the sideline during the game.
Bowles was admitted to a hospital after he experienced chest pains, was vomiting and had abdominal pains on Friday, NFL Network Insider Ian Rapoport reported. Bowles underwent tests at the hospital and was feeling better Friday night, Rapoport added.
General manager Mike Maccagnan visited Bowles in the hospital and Caldwell ran the team's walk-through Friday, a source informed of the situation told Rapoport.
Bowles, 53, is the third coach to be hospitalized during the 2016 season and could potentially be the third to miss a game this season. Broncos coach Gary Kubiak was hospitalized with a complex migraine condition in October, and Vikings coach Mike Zimmer required emergency eye surgery on Nov. 30. Each team had its special teams coach fill in.
Bowles is in his second season at the helm of the Jets. Marred by injuries and inconsistent play from the quarterback position, Gang Green has limped to a 4-10 mark, leaving Bowles with a 14-16 record in almost two seasons with the team. Before taking the head job in New York, Bowles was the defensive coordinator in Arizona, and served in an assistant or coordinator role with five different teams from 2000-2014.
