The Parramatta Eels Rugby League Club have announced that Semi has accepted an offer to play rugby union for the Toulon Rugby Club for the 2017/2018 European rugby season, with an option for a second year being the 2018/2019 season.
"In early December 2016 the Parramatta Eels indicated our wish to keep Semi at our Club by making a very attractive offer to Semi for the 2017 (upgrade of existing contract), 2018 & 2019 NRL seasons," said the club in a statement on their website.
"The offer from Toulon was substantially higher than our Club’s offer. We look forward to Semi being a most productive member of the 2017 Parramatta Eels playing squad and then we wish Semi well in his rugby union venture with Toulon."
Radradra, who has been training with the Eels this week, has scored 60 tries from 68 matches since making his debut for the Eels in 2013. He represented Australia last year.
