WATCH: Footage Emerges Of Lee Keegan Throwing Something At Dean Rock Before Winning Kick

While the celebrations are in full swing in Dublin, it would take a heart of stone not to feel sorry for Mayo after yet another All-Ireland final defeat yesterday.

However, people on social media this morning have noticed something pretty unusual about the build-up to Dean Rock's winning kick for Dublin at Croke Park.

It appears that Mayo's Lee Keegan threw his GPS tracker at the ball in an apparent attempt at putting Rock off. Take a look.

It's fair to say people aren't happy with Keegan's antics...
