Vickery has had to watch Wasps’ unbeaten start to the campaign from the sidelines as he recovered from a shoulder injury sustained on the British & Irish Lions tour of South Africa during the summer.

But the ‘Raging Bull’ will return to action tomorrow as Wasps tackle an Exiles side that have won their last two matches 40-10 and 56-7 to reinforce their reputation as the country’s most potent attacking outfit.

Wasps director Tony Hanks said: "Vicks has worked hard this summer to get through an injury and a hard fought Lions Tour.

“He is fired up and ready to make a comeback in a game which I think will be our biggest test yet.

“We have been delighted with the progress the squad have made through the first three rounds of the Guinness Premiership.

“To see the new players settle and our experienced and young aspiring guys really take our game forward has been pleasing for all involved.

“Three wins out of out three is a fantastic start but we know the bar is raised again this week against a very sharp looking London Irish team.

“There is a great feeling amongst this group and they are relishing the challenge of Sunday’s game.”

Wasps are traditionally slow starters – last year one win from six games cost them Heineken Cup qualification – but they have bucked that trend to sit top of the Guinness Premiership table with victories over Harlequins, Bath and Worcester.

Vickery returns to a Wasps side buzzing with confidence. Serge Betsen has led the side imperiously from the back row while Danny Cipriani is beginning to rediscover his best form and Tom Varndell has introduced himself to the club with five tries already this season.

But London Irish have been improving steadily week on week. From a disappointing performance on the opening day against Saracens, the Exiles last weekend blew Leeds off the park at Headingley Carnegie.
