Kyle Sinckler spent nine years at Harlequins before his move Bristol Bears.

The 31-year-old then moved to Toulon in the summer for a change of scenery to help reignite his international career on his return.

The England prop has been a big hit at the Top 14 side, starting 14 of the 16 games he has been involved in.

He said recently that the move was to help him become a better player outside of England, with a return to the national team then a possibility.

The hosts will be without influential France flanker Charles Ollivon, who has been ruled out for the remainder of the season with a knee injury.

Former England stars Kyle Sinckler (prop) and Lewis Ludlam (flanker) start in the forwards and Italy fly-half Paolo Garbisi will steer the attack.

Toulon: Domon; Drean, Frisch, Sinzelle, Wainiqolo; Garbisi, Serin; Priso, Lucchesi, Sinckler, Halagahu, Ribbans (capt), Ludlam, Abadie, Isa.

Replacements: Ivaldi, Brennan, Setiano, Alainu'uese, Rebbadj, Coulon, White, Biggar.

Harlequins make three changes for the game against Toulon.

Captain Alex Dombrandt returns to number eight and George Hammond is named in the second row.

Tyrone Green is recalled at full-back as the only other change for Quins visit of the Cote d'Azur.

Scrum-half Will Porter and fly-half Marcus Smith continue their half-back partnership with veteran number nine Danny Care named among the replacements.

Meanwhile, centre Ben Waghorn could make his European debut if he is introduced from the bench.

Harlequins: Green; David, Beard, Northmore, Murley; Smith, Porter; Baxter, Walker, Lamositele, Launchbury, Hammond, Chisholm, Kenningham, Dombrandt (capt).

Replacements: Riley, Jones, Kerrod, Cunningham-South, W Evans, Care, J Evans, Waghorn.

After a bumper day of Investec Champions Cup action, we are back with more.

Up first, Harlequins are in Toulon as they seek their second win in Europe this campaign, while Toulon look to continue their perfect start to this year's Champions Cup.

A win would qualify the Top 14 side for the last 16, with a bonus-point win for Quins all but booking their spot in the knockouts.
