Saracens number eight Ernst Joubert has announced that he will retire from rugby at the end of the month.

The 35-year-old South African has made 160 appearances for the Aviva Premiership side since moving to the club from the Golden Lions in 2009.

Joubert has helped Saracens win two Premiership titles in his six-year spell at the club, as well as the LV= Cup.

"I've had an amazing time at Saracens," Joubert told the club's official website. "There's definitely a tinge of sadness when you make the decision to hang up your boots, but I'm overwhelmed and joyful when I think of all the great memories I've made here.

"There's so many memories of my six years it's hard to single any out. Being part of the club and seeing the club grow has been a real stand out. When I came in here the club was going through a massive change up, and from that point, Saracens has become one big family.

"I never imagined in my wildest dreams that I'd be here for six years. The way the club has looked after me and my family has been amazing, and it almost makes it even more difficult to leave, but at 35 years old it's time to crack on with other things."

Joubert has also played for Western Province.
