Luton captain Tom Lockyer was brought to hospital after collapsing during Saturday's Championship play-off final.
Lockyer, who scored the winner in Luton's semi-final triumph against Sunderland, fell over while running backwards in the opening stages of the game against Coventry. A lengthy delay followed before he was stretchered off the pitch.
Lockyer, 28, was conscious as he passed through the tunnel at Wembley and received medical treatment at the stadium, with his parents rushing from the stands to see him. It is unclear what caused Lockyer's distress at this time, as he will undergo further tests.
