Sharp Gavin's return is a boost - Shane

If they come through a fitness test on Thursday then the pair are likely to start in midfield against high-flying Gloucester, a game the Ospreys have to win to keep alive hopes of reaching the quarter-finals.

Wales wing Williams is delighted to see the pair back and hopes it will help himself and Scotland's Nikki Walker maintain their top form out wide.

Williams is also celebrating having been granted a testimonial by the Ospreys this year, with a showpiece game planned for May - though Williams will hope to be preparing for the Heineken Cup final instead.

"I have been around a long time with Neath and the Ospreys, it is not just the fact I have been granted this but also a chance to put things back into the region a bit," he said.

"I have got to put the testimonial to the back of my mind a bit because we have a massive game against Gloucester this weekend - a do or die game to be honest.

"The boys were disappointed to have lost up at Kinsgholm and kind of threw it away, just made mistakes and Gloucester capitalised on that which shows what a good side they are.

"It is massive for us, the game of the season so far because we have got to win and then go out to Bourgoin and do a job.

"We have the likes of Gavin Henson and Sonny Parker who are world class. I have played outside a lot of centres and they are up there with the best.

"Gav has been training very hard since he broke his hand, Sonny has been unable to train because of his knee but has been in the gym.

"I don't think I have seen Gavin so hungry to get back and play rugby and that is great, when you have got a Gavin Henson who is hungry to play and hungry to train hard and to do well then you have a world class player.

"It will be great to see him back on the field, he is looking really sharp of the training field and we all know what type of player he is capable of being.

"It makes for exciting times, I enjoy playing next to Gav, Sonny and so on, it makes my job a lot easier.

"The bigger the game then usually the bigger the defences and people tend to tighten up, but we do not want to do that - hopefully we can carry on playing the way we have been playing when we are up against Gloucester."
