Glasgow Warriors' Al Kellock out for four months Glasgow Warriors will have to do without the services of their inspirational captain Al Kellock for the next four months after the Scotland lock underwent an operation on the arm injury he picked up during their Heineken Cup match against Cardiff Blues at Scotstoun. It is understood that the injury was a bicep tear which, although not at the most serious end of the spectrum, will keep the 32-year-old out of action for all but the last few weeks of the season. News of Kellock's absence could scarcely have come at a worse time for Glasgow. After a run of defeats and a number of off-field problems, the Warriors are anxious to get their season back on track in their two 1872 Cup clashes with Edinburgh at Murrayfield and Scotstoun over the festive period. "We are all gutted for Al to be missing out on playing for the next few months, but especially the 1872 Cup games," said Warriors head coach Gregor Townsend. He has played a prominent role in these games over the last few seasons and thrives against Edinburgh. Centre Mark Bennett is also set to miss the next few weeks after sustaining a fractured toe while playing for Scotland 7s in South Africa recently. The Warriors have dropped Niko Matawalu from their squad for the first of the 1872 Cup matches, at Murrayfield on Boxing Day.
