The most heartbreaking footy grand final defeat of 2017

It won't have landed on your sporting radar, but the Newcastle & Hunter Rugby League's Tier B Women's Grand Final produced the most excruciating finish to a team's footy season in 2017.

The Australian clash between West Wallsend and Cardiff Cobrettes produced a finish that deserves to be told in full detail, no matter how hard it is for the West Wallsend girls to relive.

If there's been a team closer to winning the big one without actually getting the chocolates, we'd love to hear about it.

Backed up near their own try line as the clock ticked down to the full-time siren, Wests simply needed to complete their final set of six to hang on to a 6-4 lead.

They played it safe, smartly choosing not to throw the ball around and with the pill in their keeping as the siren sounded the victory appeared complete.

But anyone who has played rugby league before knows the siren doesn't mark the end of the game - the ball is still live until the player holding it has been tackled (or in this case tagged) or sends it in to touch.

Unfortunately the Wests player holding the ball threw it skyward in celebration - and made a mistake she will never forget.

Cobrettes player Bryden Sloan Harris was alert to the error and pounced, grabbing the ball on the bounce, evading a desperate attempt at a tackle before charging over the line.

A 6-4 deficit became an 8-4 lead for Cardiff, whose players sprinted from all parts to congratulate their hero.

Harris shared footage of the moment on Facebook with the caption: "Holy s*** it's me hahahahaha. I will never get over this and I'm not even sorry."

Her club was equally triumphant in a post to their Facebook page. "Well done Cardiff Cobrettes on your amazing Grand Final win. The game was there to be won but when the final siren went off, it was lost!

"Due to the quick thinking and positive persistence of Bryden Sloan Harris, the team triumphed after one of the most mind boggling brain explosions you will ever see on the football field and you have to see the pics and watch the video to appreciate it. You also have to feel sorry for the Westy girls too but as "they" say, that's life!"
