Bath will be favourites to come away with the points on Sunday when they face London Welsh at the Kassam Stadium.
The West Country club have won two of their last three matches in the Aviva Premiership and are unbeaten in three in all competitions.
Their hosts have so far failed to find any consistency during their first season in the top flight and last tasted victory on home soil in the middle of September.
Tom Arscot returns for Welsh following a spell on the sidelines through injury, so Tom Voyce will move out to the wing.
Matt Banahan in back for Bath and will play his first match since the second weekend of the season.
Anthony Perenise, Stuart Hooper and Will Skuse are also given berths in the starting lineup in place of David Wilson, Carl Fearns and Francois Louw.
