Richard Hill's return could not help Saracens qualify for the Parker Pen Challenge Cup semi-finals despite an 18-14 win over Montferrand.
England star Hill could not save Saracens
Sarries won the second leg at Vicarage Road with six penalties from Fijian
fly-half Nicky Little.
But the 16-point deficit from the first leg, won 26-10 by Montferrand in France, proved elusive.
Montferrand will play Bath, while Harlequins will meet Connacht in the last four of the competition.
Bath beat France's Beziers 26-7 at The Recreation Ground on Saturday to book their semi-final berth.
The former European champions won 45-31 on aggregate after reversing a five-point deficit from last week.
First-half tries from wing Alex Crockett and fly-half Olly Barkley gave Bath a 18-0 lead at the break.
Bath's Barkley scored a try and kicked 11 points
And despite losing skipper Danny Grewcock to the sin-bin early in the second period, Scot Simon Danielli added the gloss with a late score.
England hopeful Barkley converted his own try and added three penalties, while number eight Lionel Camisuli grabbed a consolation for Beziers.
In France, Harlequins lost 36-20 to Brive but the 33-point advantage from the first leg was enough to see them through.
Samoan centre George Harder scored Quins' first try and former Ireland international Paul Burke kept the scoreboard ticking over with three penalty goals.
Brive hit back with two tries to take a 22-14 lead at half-time and another try to Brive winger Yves Donguy immediately after the
resumption rattled Quins further.
But two more Burke penalty
goals settled the nerves and ended Brive's charge, despite 18 points from scrum-half Valentin Courrent.
Connacht qualified for their first European semi-final after coming from behind to beat Narbonne 16-10.
The Irish side won 43-38 on aggregate with tries from full-back Mark McHugh and Australian lock Andrew Farley.
Connacht trailed 10-3 at the break after a try from Nicholas Nadau.
But McHugh rumbled over for Connacht's first try on 65 minutes and Farley's unconverted try three minutes from the end secured the win.
In the Parker Pen Shield quarter-final second legs Rotherham edged Viadana 22-21, Petrarca won 18-9 against Montpellier, Rovigo beat Parma 24-20 and Leonessa defeated UE Santboiana 28-10.
