Harlequins have made two changes to their starting line-up for their Champions Cup clash with Castres at Stade Pierre Antoine on Saturday.
Nick Evans makes his first start for the club since the Round 3 match against Leinster, having made a replacement appearance last weekend, while Charlie Walker is named on the wing, in his first European start of the season.
In an unchanged forward pack, hooker Joe Gray makes his 100th appearance for the club, becoming the 14th current Harlequins squad member to do so.
Meanwhile, Castres welcome back Remi Grosso to their starting line-up as he takes Romain Martial’s place on the right wing, with Remi Tales and Antoine Dupont also named at fly-half and scrum-half respectively.
France international Rory Kockott is not in the matchday 23, with Castres hoping to claim their first win of the 2014/15 Champions Cup campaign
Form: Castres were hammered 50-8 by Leinster last week and have yet to win a European game this season. In their last home outing, they beat La Rochelle 30-15. Quins were beaten 23-3 at home to Wasps last week but were 32-12 winners over Leicester in the Premiership a week earlier.
