Leicester 21 Stade Francais 20: Leicester kept alive their hopes of an unprecedented trophy treble by stunning French Championship leaders Stade Francais to book a place in the Heineken Cup semi-finals.
Substitute Tom Varndell's 72nd-minute try, which was converted by outhalf Andy Goode, sent Tigers through to a last-four appointment with Welsh challengers Llanelli Scarlets at Walkers Stadium in three weeks' time.
Leicester's victory also means England will have a record three clubs in the semi-finals after Northampton shocked Biarritz and booked a clash against 2004 European champions Wasps.
But France, despite their national team winning this season's Six Nations Championship, have failed to produce a representative in the penultimate knockout round.
The Tigers are also on course for a Guinness Premiership play-off place, and they will contest the EDF Energy Cup final against the Ospreys at Twickenham on April 15.
But they left it late to send Stade spinning out of Europe, taking charge just when it looked as though outhalf David Skrela - who slotted four penalties and a drop-goal - would steer the Parisians through.
Full-back Juan Martin Hernandez, the game's outstanding back, scored a first-half try, but Varndell came up trumps when it mattered following an early touchdown by Seru Rabeni. Goode kicked 11 points.
