Warrior Kellock so emotional at decision to retire
Al Kellock's announcement that he is to retire comes with his Glasgow side battling it out with Ulster at the top of the Guinness PRO12 table.
The 33-year-old lock will hang up his boots at the end of the season after leading Warriors - two points clear of Ulster - for nine years and earning 56 caps for Scotland.
Kellock, who joined Glasgow from Edinburgh in 2006, said: "I feel the time is right for me to retire and it's an emotional and reflective time for me.
"I've always had a rule of playing every game like it's my last as you never know when that will be, but now I can see it coming pretty quickly, after 17 years playing senior rugby.
"I'm excited about the next chapter but there are so many things that I'll miss massively, especially the times in the changing room before and after a game.
"The supporters have been great with me and I hugely appreciate the backing they've given me throughout my career.
"When I first joined the club we were bringing in 1,500 people at Hughenden, but now we're regularly exceeding 6,000 at Scotstoun, which makes me incredibly proud and happy to be part of the journey.
"To have captained the side for nine years is such an honour and I have so many fantastic memories, such as beating Toulouse away from home in Europe and winning against Munster in the Pro12 semi-final last season when my daughter was mascot."
Kellock will continue to work for the Scottish Rugby Union and Glasgow Warriors, with his tasks including engaging with the rugby and business communities and learning more about the commercial aspect of the sport.
"My new role allows me to help Scottish Rugby grow through the ambassador role, while continuing my involvement at Glasgow Warriors," he said.
