Northampton v Wasps preview
Northampton Saints host London Wasps in the Aviva Premiership on Friday night, with Dom Waldouck back for the hosts against his old club.
Unbeaten Northampton show two changes from the side that defeated Worcester five days ago.
Centre Waldouck, who switched from Wasps to Saints in the summer, replaces George Pisi alongside Luther Burrell in midfield and England flanker Tom Wood features at openside instead of Phil Dowson, who is on bench duty at Franklin's Gardens.
Prop Tim Payne will make his 250th appearance for Wasps as the Londoners look to bounce back from last weekend's defeat at Gloucester.
Wing James Bailey makes a first-team debut, replacing Tom Varndell, while there are also starts for fly-half Nicky Robinson, flanker Joe Launchbury and number eight Billy Vunipola.
