Sam Warburton has been overwhelmed by the support following his surprise retirement from rugby.

Warburton brought an end to his time in the sport on Wednesday, surprisingly hanging up his boots having previously been expected to return from injury and join Cardiff Blues for pre-season training.

The flanker had been recovering from neck and knee surgery following his last international appearance against New Zealand in June 2017 but was not confident he could rediscover his best form.

Warburton was capped 74 times by Wales and captained his country on a record 49 occasions, leading them to a Six Nations Grand Slam in 2012.

He also captained the British and Irish Lions for their 2013 series win over Australia and the 2017 drawn series with world champions New Zealand.

The 29-year-old wrote on Twitter: "Never in a million years expected this much support. I cannot put into words how much it means to me.

"Reading all the lovely messages has been genuinely overwhelming. It's been an emotional 24hrs, but confirms that the rugby family we are in is amazing."
