All the team news ahead of this weekend's Guinness Premiership games.

Harlequins v Bath (Sunday)

Harlequins make two changes from the starting XV which lost at Wasps last week. De Wet Barry replaces Tom Masson at inside centre, and Simon Keogh comes in for Tom Williams on the wing.

Their opponents Bath line up with props Duncan Bell and David Flatman paired together for the first time since October 2006. In the backs, Nick Abendanon and Matt Banahan replace Joe Maddock and Andrew Higgins.

Newcastle Falcons v Bristol (Sunday)

Sam Cox replaces the injured David Hill (neck) at inside centre, with Tom Arscott in for David Lemi (calf) on the wing. Forwards Scott Linklater, Jason Hobson and captain Matt Salter have also done enough to return to the starting line-up.
