Harlequins return to the Stoop on Saturday to welcome Sale Sharks after a hard fought victory away at Worcester - which saw them retain their place at the top of the Aviva Premiership standings.
There is only one change to the side that started last week against Worcester.
Mike Brown and Sam Smith will be partnered this week by Seb Stegmann, who replaces Ugo Monye. Monye came off against Worcester with a knock but is expected to be fit for the visit to Welford Road next week.
Jordan Turner Hall and George Lowe remain in the midfield, alongside Nick Evans and Karl Dickson who continue at half-back.
The starting pack remains in tact from Worcester, with Olly Kohn making his 100th competitive appearance for the club.
The bench sees the return of Joe Marler (from suspension) and James Johnston (from a recent injury) as front row replacements. Will Skinner also returns from injury, and Tom Casson re-enters the fold from his injury sustained in pre-season.
The 23 man squad continues to show home grown English talent at its spine with 21 English Qualified Players and 10 of the starting line up having graduated from the Quins academy system.
Meanwhile, Sale have made two changes, one positional, to the starting fifteen for this weekend's Round Five clash.
Sharks captain Sam Tuitupou, who made his debut from the bench last week, starts at inside centre with Will Addison switching to number thirteen.
