Why was a circle red card shown?

But why?

Circular red cards are something we saw for a short phase in the Premier League during the early 2000s.

And there's a reason for it.

As explained on a referee forum, it's both to 'assist' colour blind fans but also for the benefit of the referee himself.

“The circular and oval cards were originally introduced to “assist” players who couldn’t differentiate between the colours. It was also to help the referee who wanted to pull out the quick card, the shape telling him which card he was pulling out.”

There we have it.

We're all for a circular red card.

Back to the cup tie at Wrexham and the home side thought they had won it when Paul Mullin finished a chance with just minutes remaining.

But in the fifth minute of injury-time John Egan broke the hearts of Wrexham fans to make it 3-3.

Ryan Reynolds: Wrexham are targeting the Premier League

Wrexham, of course, are co-owned by Hollywood stars Ryan Reynolds and Rob McElhenney.

And before the tie, Reynolds made a "crazy" promise to Wrexham fans.

"We want to walk the walk, even as a fifth-tier club," he said.

"We say this all the time, but we want to be in the Premier League, as crazy as that sounds to some people. If it is theoretically possible to go from the fifth tier in professional football all the way to the Premier League, why wouldn't we do that? Why wouldn't we use our last drop of blood to get there? We're in it for the ride. This is a multidecade project."
