Scrum-half Will Porter replaces Danny Care for Harlequins' Investec Champions Cup game against Toulouse on Sunday.

Fly-half Marcus Smith stood out, with his 16-point haul including a drop-goal from near the halfway line, and he is retained in the starting XV.

Prop Will Collier has recovered from injury to start in the front row.

The experienced Collier packs down with Joe Marler and Jack Walker, while flanker James Chisholm earns his first start of the season.

Toulouse recorded the highest winning margin of any side in the opening Champions Cup games, with a 52-7 victory against Cardiff Blues.

Scotland full-back Blair Kinghorn scored two tries on his Toulouse debut and retains his place.

Despite Antoine Dupont's announcement that he will focus on the World Rugby Sevens Series in 2024, the Toulouse captain remains at scrum-half.

The French side are sixth in the Top 14 but remain the only side to have won five Champions Cups.

Ulster, Bath, Racing 92 and Cardiff are the other sides in Pool 2.
