The game, which ended in a 3-2 win for Sheffield Wednesday, continued despite the incident.
A football fan has died after suffering a "medical emergency" at West Brom’s away match at Sheffield Wednesday on Saturday.
West Brom released a statement to say the team was "devastated to learn of the tragic passing" of their supporter "following a medical emergency" during the game at Hillsborough.
"The club has made contact with the supporter’s family to pass on its condolences and asks that they are allowed to grieve privately," it added.
"The thoughts of all of us will remain with the supporter’s loved ones at this desperately sad time."
The supporter became unwell during the first half of the match, with hundreds of away fans gesturing for stewards to assist them and calls to stop the game.
It was allowed to continue, however, and finished in a 3-2 win for Sheffield Wednesday.
