Luton captain Tom Lockyer collapsed on the field for the second time this year after suffering cardiac arrest, prompting the abandonment of their English Premier League game at Bournemouth.
Lockyer was taken to the hospital on Saturday and was "stable and currently undergoing further tests with his family at his bedside."
The Wales defender dropped to the ground untouched in the 59th minute.
Players from both sides immediately called for help and Luton manager Rob Edwards entered the field, looking distressed.
The 29-year-old received a long period of medical treatment and was carried away on a stretcher, by which time he was responsive.
The score was 1-1 at the time and referee Simon Hooper made the decision to abandon the game, with the clock having stopped in the 65th.
Fans stayed behind at Vitality Stadium after the match was called off and chanted the name of Lockyer.
Lockyer first collapsed during the Championship playoff final at Wembley in May because he suffered an atrial fibrillation. He underwent surgery and was given the all-clear during the offseason.
There was a very different kind of drama at Etihad Stadium, where Manchester City threw away a two-goal lead and drew with Crystal Palace in its increasingly unconvincing title defense.
The equalizer came in the fifth minute of stoppage time via a penalty from Michael Olise as City drew a third straight home game. The champions have won just one of their last six league games. City was 2-0 ahead through goals by Jack Grealish in the 24th minute and Rico Lewis in the 54th.
Jean-Philippe Mateta reduced the deficit for Palace in the 76th. Phil Foden then tripped Mateta to give Olise the opportunity to grab a point for Palace, which lost six of its previous eight league matches.
Fatigued, hindered by a slew of injuries and hurting after a Champions League exit, Newcastle wasn't in a good place ahead of the visit of a Fulham team coming off back-to-back 5-0 wins.
The Saudi-owned team was given a helping hand courtesy of a red card to Fulham striker Raul Jimenez, who was sent off for a dangerous challenge in the 22nd minute, and went on to win 3-0.
Chelsea beat Sheffield United 2-0 thanks to goals by Cole Palmer and Nicolas Jackson.
It was the same score at Turf Moor where Amadou Onana and Michael Keane netted in Everton's win at next-to-last Burnley to move seven points clear of the bottom three.
