Captain Tom Lockyer celebrated Luton's promotion to the Premier League in hospital with family and friends after collapsing during the Championship play-off final.
Lockyear fell to the ground untouched while backpeddling early in the game at Wembley and then seemed to collapse as he tried to get back up.
The defender received medical attention for several minutes before being carried off on a stretcher.
Luton said on Twitter that 'after collapsing on the pitch, Tom Lockyer has been taken to hospital for further tests. He is responsive and talking to his family, who are with him.
