Saturday's Premiership teams: Anthony Watson starts for Bath

There are two games in the Aviva Premiership on Saturday as Bath host leaders Wasps and Gloucester face Harlequins at Kingsholm.

A number of international players return to club duty, including wings Anthony Watson and Tim Visser, while Ashley Johnson reaches a Premiership milestone.

Bath v Wasps (3pm)

Bath welcome back international trio Anthony Watson, Luke Charteris and Taulupe Faletau for Wasps' Recreation Ground visit.

Adam Hastings and Chris Cook form the half-back partnership while wing Kristian Phillips, who is on trial at the club, will make his debut if he features off the bench.

Wasps make a solitary change from the side that saw off Gloucester. Kyle Eastmond's season-ending Achilles' tendon injury results in Jimmy Gopperth moving back to inside centre and Alapati Leiua wearing the No 13 shirt.

Versatile forward Ashley Johnson makes his 100th Premiership appearance.

Gloucester v Harlequins (3pm)

Fly-half Billy Burns returns for Gloucester as one of four changes following the defeat to Wasps.

Burns features as the only back division switch while up front there are starts for props Yann Thomas and John Afoa plus lock Mariano Galarza, who takes over from Tom Savage.

Harlequins will be without fly-half Nick Evans for three weeks while he recovers from a shoulder injury so Tim Swiel wears the No 10 shirt.
