YOU need a big man for a big occasion ...

and, in Al Kellock, Glasgow have the perfect fit for today's monumental match against Ulster.

The Belfast side come to Scotstoun this afternoon in the final regular game of the Guinness Pro12 season as both teams go for one of the two home play-off semi-final slots up for grabs.

The arithmetical permutations are extensive, but only a point separates Ulster from joint leaders Ospreys, Glasgow and Munster.

Knowing the importance of this afternoon's tie, where a bonus point win would guarantee Warriors one of the places, head coach Gregor Townsend has recalled club captain Kellock to lead his men into battle in front of a sellout 10,000 crowd.

It could be the 6ft 8in giant's last game in front of his home crowd before he hangs up his boots in the summer, but Townsend is hoping his huge influence can help make sure it may be his second last.

"He brings a lot of intelligence in how to manage a game," said Townsend, who recalls Kellock in place of the injured Tim Swinson.

"He helps the nine and 10 with the decision-making. He has a calming presence. He is obviously a very strong lineout operator in attack and defence. He is very good at finding out what the referee wants from the team.

"You have 16 or 17 years of exper-ience there and also a passion for the club. It is really pleasing for me that he is playing well. That is the first thing anyone has to do to get into the team."

It is an occasion the man himself is desperate to be a part of. Against Cardiff Blues last month, Kellock was given the opportunity, along with exiting team-mate Dougie Hall, to say goodbye to the Scotstoun crowd in style. Along with his children Ruaridh and Kate, the 33-year-old walked out to a standing ovation for what many considered to be the last time.

He, however, wasn't one of them.

"The Cardiff game was the tribute game!" joked Kellock. "I knew after that match there was the potential I'd be playing again and the focus for me was to make sure I maintained my fitness and worked as hard as I could.

"I've learned to deal with not being in every week over the last year-and-a-half, but you don't give away anything cheaply.

"I've been training as hard as I can and making a nuisance of myself, and I'm really looking forward to the game. It is massive."
