The Australian Emus produced an unbelievable comeback victory on Sunday at the U19 Basketball World Cup in Switzerland after Cameroonian player Amadou Seini dunked the ball into his own team's basket.
Australia had been six points down with just 48.9 seconds to go in the final quarter when the bizarre incident took place.
Seini had moved back towards his team's baseline to receive a pass from a team-mate to restart play.
However, upon receiving the pass, Seini leapt up and dunked the ball into his own net.
The move left his team-mates gobsmacked, with some members of the Cameroon side raising their hands to their heads in disbelief at centre's mistake in conceeding two points against his own team.
Australia would then go on to draw level 83-83 at the end of regular play and force the match to extra-time.

A Cameroon U19 basketball player left his team-mates shocked on Sunday as he bizarrely dunked the ball into his own basket
The incident came just 48.9 seconds before the end of full-time with Cameroon holding the lead against Australia. However, Australia would pull back the victory in extra-time
The Emus then mounted a late surge to seal a 101-96 victory after double overtime.
While a very rare occurrence, it is not the first time a player has scored in their own basket.
Back in 2013, University of Kentucky star Joe Young had attempted to stop the ball from going out of bounds.
In his attempt to flick the ball away from the touchline, it dropped into his own net.
Earlier this year, point guard Marie Pardon was playing for Landes Basket in France's top division, when she too made the same error.
Her side had been taking on Tarbes in the final game of the season, when an opposition player had a long shot at the basket.
With only seconds to go, Pardon had thought the half-time buzzer had sounded before catching the ball.
The French point guard mistakenly chucked the ball into her own net, appearing to practice her shooting not realising that the ball was still live. Despite the error, Landes Basket would go on to seal the win in the second half.

Meanwhile, referees stepped over to the touchline to discuss the very rare moment
The Emus, meanwhile, have moved up to third place in Group D after they had suffered an 88-73 defeat by USA in the opening round of the tournament.
Alex Dickeson, who struck five baskets from 13 attempts, levelled the game before the end of regulation time, before firing in another three-pointer in the first quarter of extra-time.
Goc Malual, Roman Siulepa, Dash Daniels and Che Dean Miller Brogan would follow up with baskets for the Aussies in the second term, to seal the victory.
Australia return to face France on Tuesday in their third group game, while Cameron will also take on the USA in Lausanne.
