Andy Farrell is to retire from professional rugby at the end of this season.

The former Great Britain and Wigan rugby league captain switched codes in 2005, joining Saracens and going on to win eight caps for England, including being part of their 2007 World Cup squad.

He will remain at Saracens, taking up a role as skills coach with the Guinness Premiership club.

Farrell, 34 next month, enjoyed an 18-year playing career across both rugby codes.

He said: “My mind still feels as sharp as ever, but my body is telling me different things.

“Throughout my career I’ve always prided myself on doing extra training to stay one step ahead of opponents, but I’m now finding myself spending all my time just trying to get right for training, rather than trying to be a better player.

“When that time comes, it is time to stop.

“After 18 years, it will be an emotional moment to play my last game, but I’m really excited about the opportunity that Saracens have given to me to move into coaching — something I have always wanted to do.

“I’ve always been interested in coaching, and I’ve been lucky enough to work with some fantastic people during my career and I’m looking forward to putting into practice all the knowledge I’ve gained over the years.”
