Former surfing star Chris Davidson died on Saturday ... after he was allegedly punched in the face in an altercation outside of a bar in Australia.
He was just 45 years old.
Authorities say they responded to a South West Rocks pub at around 11 PM on Saturday after receiving calls about an assault. A man -- reportedly later ID'ed as Davidson -- had allegedly hit his head on the ground following a punch.
According to the officials, when they arrived, they found the man unconscious. They say he was transported to a nearby hospital, but died a short time later.
Police say they've arrested a 42-year-old man in connection with the incident. He has since been charged with assault causing death.
Davidson had initially gained fame in the sport in the 1990s ... and eventually earned a #14 world ranking in 2010.
Surfing legend Kelly Slater mourned his death in a post on his social media page, saying, "Lost another soldier yesterday. #RIPChrisDavo."
"Had many a good battle with this guy," Slater added. "One of the most naturally talented surfers I ever knew."
Surfing Australia called Davidson "an incredibly talented surfer and a true individual in our sport and community."
"Our thoughts go out to his two children, friends and family at this time," the org. added.
RIP.
