Luton Town say Tom Lockyer suffered a cardiac arrest but is "responsive" in hospital after the defender collapsed on the pitch during their Premier League match at Bournemouth, with the club praising the "amazing" response of medical staff during Saturday's abandoned game.
Both sets of players returned to their dressing rooms as centreback Lockyer, 29, received medical treatment midway through the second half of the game at Vitality Stadium.
Lockyer was taken off on a stretcher after several minutes of attention, with widespread initial reports quoting Bournemouth's staff doctor as saying the Wales international was "alert and responsive" in the tunnel.
The former Charlton Athletic player collapsed during the Hatters' Championship playoff final win against Coventry City in May but was given the all-clear to return to playing in June.
The fixture between AFC Bournemouth and Luton Town has been suspended.
All our thoughts are with Tom Lockyer at this time.
