It has since been confirmed that the supporter died in hospital with both managers saying concurring that it was certainly the right decision to make.
"Obviously it was quite serious so Pat Fenlon and I both agreed that the game should be abandoned," Shiels said.
"We need to show respect to the relevant families. Football is not as important as human life so we have shown our respect."
