|Montpellier lead 40-26 after first leg|
Will Evans replaces Tom Lawday as openside flanker. Harlequins are trying to overcome a 14-point deficit with French high-fliers Montpellier to make it to the Champions Cup final eight.
Joe Marchant and Andre Esterhuizen make a strong backs pairing.
For Montpellier, Zach Mercer, English number eight, drops to the bench.
The 24-year-old scored 2 tries and was named man for the match
Springbok Handre pollard joins the team as an inside centre. This is in addition to his usual fly half role. France international Guilhem Guirado is back at hooker.
If Harlequins manage to complete their comeback at Stoop they will face French opposition in the quarterfinals. This year's runners-up Bordeaux-Begles and La Rochelle are waiting.
La Rochelle are favorites to win the next leg, with a record 31-13 aggregate score before their home leg.
Adam Jones, Harlequins scrum coach:“It's not over, I think, if we look back over our results over the past 18 months.
“The performance in the first half was not good enough. However, to only be 14 points down overall and have 34-0 at 50 minutes isn't too bad.
“Montpellier likely felt they needed more than a 21-point lead, so I'm sure they will be a bit frustrated. However, we know that they will be tough opponents back on the Stoop.”
