Jonny Gray has been handed the Glasgow captaincy - hours after signing a new three-year contract.

Warriors have confirmed the 21-year-old will succeed Al Kellock, who retired at the end of their Guinness Pro12 title-winning campaign.

The Glasgow-born lock captained the club for the first time in an away victory over Connacht in April and now gets the role on an ongoing basis.

The Scotland international told his club's website: "I'm hugely honoured to have been named captain of Glasgow Warriors.

"I grew up supporting Glasgow and it means a lot to have been given the opportunity to captain the club, following in the footsteps of an inspirational leader like Al.

"It's a very special day for me and my family and I'm really looking forward to leading the team."

Warriors head coach Gregor Townsend added: "Jonny has shown leadership qualities right back to when he was in the BT Sport Scottish Rugby Academy and had his first taste of rugby as a professional.

"He is someone who seeks out information and relishes taking on challenges. He did very well when he captained the side last season away to Connacht, in a difficult environment.

"Al became the captain at a young age and grew into the role to become an outstanding leader of men. Jonny will lead in his own way but already has the respect of the playing and coaching group by the way he conducts himself.

"The captain is one aspect of our leadership group and what excites me is that there are a number of leaders in our squad, setting standards, supporting and challenging their team-mates on a daily basis.

"It's great for Jonny that he knows he'll have the likes of Josh Strauss, Rob Harley, Peter Horne and Chris Fusaro supporting him."
