A Northern Ireland fan has died at the Stade de Lyon after collapsing during their Euro 2016 match with Ukraine on Thursday.
The man, in his sixties, collapsed in the upper part of the ground and was treated by paramedics but they were unable to revive him.
Northern Ireland won the match 2-0, but Irish FA boss Patrick Nelson said: "This puts any result of a football match into perspective. The thoughts of the board, management, players and staff are with his family and friends at this sad time."
Superintendent Nigel Goddard said: "Our thoughts are tragically with a second family this week mourning the devastating loss of their loved one.
"We understand the man aged in his sixties collapsed during the game and was attended to by emergency services in the Stade de Lyon.
"It is extremely sad that this is the second death of a Northern Ireland fan in France during the Euro 2016 games."
On Sunday, Darren Rodgers, 24, died after falling from a promenade in Nice in the hours after the Irish began their finals with a 1-0 defeat to Poland.
Northern Ireland's players wore black armbands during the Ukraine game and their fans applauded Rodgers' memory in tribute in the 24th minute.
