British and Irish Lions

The inspirational Lions centre sustained a hamstring injury in Leinster's dramatic 23-22 home defeat by Sale Sharks in the Heineken Cup pool three match at Lansdowne Road on Friday night.

The Blackrock College player, who limped off just 18 minutes into the game, has undergone a scan and has been told he faces a lay-off of between four and six weeks.

"While this injury may jeopardise Brian O'Driscoll's participation in the start of the RBS 6 Nations campaign, the Irish management are not ruling him out at this stage," said a spokesman.

Lions skipper Sam Warburton says the lessons he and his Welsh colleagues learnt in Australia last summer will stand them in good stead for their return visit with Britain and Ireland's elite next month.

Tom Youngs has enjoyed a remarkable rise to the top of the British & Irish game but he won't be resting on his laurels ahead of his first Lions adventure.
