However, many of them decided to go elsewhere on Saturday afternoon to get their footballing fix, from The New Saints and Marine to Manchester City and Aston Villa.
We asked those on X, formerly Twitter, to send across their photos from the games they attended instead of Blackburn – with 16 different grounds mentioned.

5. Preston v Derby
Lee Laver; Preston v Derby for me and the boy. We can finish above both of these. More atmosphere on the moon as well. Photo: None
7. Everton/Liverpool
@oscarcollier19: We tried to get into Everton's game but unfortunately tickets were sold out, so we had a stadium tour round Anfield instead. Photo: None
8. Bolton v Blackpool and Manchester City v Spurs
@Bnewitt9: Went to Bolton vs Blackpool in the away end, someone on my train to Manchester had a spare ticket. Also City vs Spurs. Made the most of it. Photo: None
