This is how not to celebrate a winning season.

Brazilian side Sertaozinho experienced a horrific accident on Sunday when their open-top bus celebrations turned into a nightmare as their bus toppled over with the players onboard.

The incident occurred when the rickety vehicle, carrying more people than was reasonable, fell into a dip in the road. Unable to regain its balance, the bus fell on its side. Its footballers all tumbled to the ground.

Sadly, there were serious injuries. There were reports of broken limbs and one player was said to have severely damaged his spleen.
