Boks' Louw to quit international rugby

South African World Cup-winning forward Francois Louw (R) will retire from international rugby

South African loose-forward Francois Louw has announced his retirement from international rugby, the second of the Springboks' World Cup-winning side to call time on their careers.

Louw, who came off the bench for captain Siya Kolisi in the 32-12 victory over England in the November 2 World Cup decider, won 76 Test caps after debuting in 2010.

"I couldn't have asked for a more fulfilling career with the Springboks and I bow out with a full heart," he said in a media release on Sunday from South Africa Rugby.

"I've had an amazing journey in international rugby. I've made friends for life in the game and created incredible memories with great people."

South African coach Rassie Erasmus praised Louw's contribution to their World Cup campaign.

"Flo was a real warrior of the back row. He was always ready to go where the fire was hottest and was the kind of tough-minded character that you'd always want beside you," Erasmus said.

"He has been a tremendous servant of South African rugby and we're losing a lot with his retirement, not just in how he played, but in the calmness, insight and character that he brought to the group."

Louw's retirement follows that of Tendai Mtawarira. The prop won the last of his 117 caps in the World Cup final.
