Trainer's 'Dad Fail' almost ends in catastrophe

Prominent horse trainer Bjorn Baker was trying to show he was a cool dad when a backyard mishap almost ended in disaster.

The NSW trainer uploaded the above video to his Twitter account on Thursday, showing him attempting to dunk a basketball in the backyard of his home.

The Music Magnate trainer completed the dunk, but in a heart-stopping moment, he inadvertently landed on an exercise ball rolled underneath him by his young son.

Baker's feet landed on the ball, causing him to flip and hit his head on the paved ground.

Thankfully Baker jumped to his feet straight away, but things could have been much worse had he landed differently.
