Wales captain Sam Warburton has hailed the professionalism shown by fly-half Dan Biggar in his recovery from an ankle injury over the past week.

Biggar was forced off with a sprained ankle after just 20 minutes of his side's 16-16 draw with Ireland in their opening game of the Six Nations last weekend, with Wales initially fearing that their kicker could miss a large chunk of the tournament.

However, he has been included in the side to face Scotland at the Millennium Stadium on Saturday after what head coach Warren Gatland called a "miraculous" recovery, and Warburton joined his manager in praising the 26-year-old.

"He was barking instructions and back to his usual self [on his return to training on Thursday]. It is great that he has made a good recovery - it just shows what a great professional he is," Warburton told reporters.

"A lot of people won't see the late nights on the ice machine and then all the way through the night, probably not stringing together more than two hours' kip at one time, and being with the physios when everyone is having a couple of days off.

"You have got to give him a lot of credit for the way he has worked. If an average person just sat back and didn't really do anything, you would be probably be out for three weeks, but because he is such a diligent professional, he has managed to get back so soon."

Wales will be bidding for a ninth consecutive victory over Scotland this weekend.
