Trio of burly wrestlers lose tug of war to young lion at San Antonio Zoo

Three muscular wrestlers have faced off against a lion in tug of war match and lost.

Professional wrestlers Ricochet, Fabian Aichner and Killian Dain all tried to best the young cub at San Antonio Zoo, but they could not get it to move at all, the Daily Mail reports.

The tug of war set up was installed as part of the zoo's expansion of big cat enclosures and allowed any member of the public to try their strength against the cats.

Video shows the trio on one side of the reinforced glass pulling with all their might as the young lion stands on the other side, refusing to move a centimetre.

"Just let us know when you are ready to tap out!" a staff member could be heard saying as the men struggled.

Eventually they gave up and let go of the rope, admitting defeat to the big cat.

The video was posted to Facebook by the zoo, explaining the lion in the picture was only two-and-a-half years old.

"How many superstar wrestlers does it take to win in tug of war with a 2 1/2 year old lion cub?" the caption read.

"Apparently more than 3!"
