Southwell returns for Wasps
Wasps captain Hugo Southwell will make his return from a hand injury in Sunday's Aviva Premiership clash with Worcester at Adams Park.
The full-back has missed his side's last two games but is back in the starting XV as one of three changes to the back-line for the visit of the Warriors.
Stephen Jones takes the No 10 shirt after being forced to miss the defeat to Northampton with a stomach bug, and Tom Varndell returns on the wing in the place of the injured James Bailey.
Only one change is made in the forwards, with Simon McIntyre replacing the suspended Tim Payne in the front row.
Jon Clarke will make his first start for Worcester, coming in on the wing for Nikki Walker in the only change to head coach Richard Hill's starting XV following the victory over London Irish.
