Thirty-seven times capped South African wing Stefan Terblanche has joined the Ospreys on a two-year contract.
Terblanche played for the Springboks in the World Cup
The 28-year-old, who has 19 Test tries to his name, joins the west Glamorgan regional side from Natal Sharks.
Terblanche last played for the Springboks against Georgia during the World Cup in Australia and still holds the South African record for most tries in a match - five against Italy in Durban in 1999.
The Ospreys hope that the 6ft 2, 15-stone winger will join the squad within the next seven days.
"We are delighted that a player of Stefan's experience and ability has agreed to become part of Ospreys rugby," said head coach Lyn Jones.
"He arrives with a huge pedigree and reputation and it is up to him to show what he can do when he links up with us.
"He has a strong all-round game but his greatest strength is his natural speed, which will be useful not just in attack, but also in defence.
"He has proven himself at the highest possible level and will further enhance our attacking options."
The Ospreys' joint managing director Mike Cuddy added: "We will always look to improve the strength of the squad, and we have been looking for a wing for quite some time.
"Stefan is a world-class player, who will exactly fit the expansive style of play Lyn has adopted.
"We have an exciting few weeks ahead, with the return of the World Cup players and now with Stefan's addition to the squad."
