Shrewsbury Town's League Two home game with Port Vale was abandoned after 64 minutes due to a fire in the East Stand generator room at the Greenhous Meadow.
Promotion-chasing Town were leading 1-0 thanks to a well-taken 50th-minute strike from top scorer James Collins.

"The main thing is nobody was hurt and it all went smoothly but we're in shock. We can't believe this has happened. It was one of our best performances of the season and we were playing some great football.
"We've just got put it to behind us, take the positives out of our performance and look forward to Saturday and try to take it out on Aldershot."
