Mike Hodge, with his wife, Chrissy.
Shocking footage of the incident shows the lion chasing Mr Hodge after he enters the enclosure and then dragging him towards some bushes.
Hodge, who left the United Kingdom for South Africa with his wife Chrissy in 1999, is believed to have suffered neck and jaw injuries stemming from the altercation.
A terrifyingly video that has gone viral since the event shows a 67-year-old man Mike Hodge getting mauled by a full-grown lion after Mr Hodge went too close to the ferocious animal inside his enclosure.
The park remains closed and the lion is believed to have been put down.
The lion is finally scared away by gunshots, leaving the man's motionless body lying in the bushes.
It has become a routine of a sort to step inside animals' enclosure, a mistake that could have proven fatal for Briton owner of Marakele Predator Park in South Africa.
The man, whose face has been blurred in the footage, then tries to sprint for the door, but is caught by the massive cat, which drags him away as he pleads for help.
One of 33 lions rescued from circuses in Peru and Columbia is released at its final destination: an animal sanctuary in South Africa's Limpopo province.
"It had put the lion on edge but when Mike went in the lion turned and came for him and he ran but couldn't get through the gate quick enough and it had him", said Mike.
In the background a man can be heard shouting 'get a rifle'.
Debbie Wagner said: 'So sad that the lion is only doing what comes naturally to him.
Shamba was killed after the attack, a family friend, Bernadette Maguire, told The Telegraph.
