BRITISH and Irish Lions captain Sam Warburton will make his comeback from injury for Cardiff Blues this weekend.

The flanker will feature against Leinster in Dublin on Friday night, his first appearance since tearing a hamstring in the second Test against Australia in June.

The 24-year-old was expected to be out for up to four months but is back ahead of schedule, much to the relief of Phil Davies.

The Blues director of rugby is under pressure after a home defeat to Zebre last weekend - the Italian side's first win at the 31st time of asking.

"Sam wanted to play. He himself has done a phenomenal job, as have the medical department," said Davies.

"He's five weeks ahead of schedule and that's down to his diligence. He was knocking the door down to play which is fantastic. It's really exciting."
