Former Chelsea defender Sam Hutchinson had heart surgery having experienced complications after a League Two match earlier this month.
The AFC Wimbledon defensive midfielder scored the winning goal against Grimsby which secured the Dons' place in the play-offs.
Hutchinson played the full 90 minutes but complained of chest pains during his post-match interview. He was taken to hospital on the journey back where he was treated and assessed in Queens Medical Centre and City Hospital in Nottingham.
'To be fair, I felt like rubbish during the game for some reason. I had a really tight chest,' he said after the match.
