Rassie Erasmus hailed Francois Louw as a "warrior" after the South Africa back-row announced his international retirement.

The 34-year-old has called time on his Test career on the back of the Springboks' Rugby World Cup triumph in Japan.

Louw played 76 times for the world champions and Rugby Championship holders after making his debut against Wales in 2010.

South Africa director of rugby Erasmus paid tribute to the forward, who will continue to play for Premiership side Bath.

Erasmus said: "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. He didn't take a step backwards ever.

"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 said: "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."
