Ospreys 15 Leicester 9:The Tigers scraped into the Heineken Cup quarter-finals — and left Ospreys sweating on a last-eight place — despite losing an intense Liberty Stadium encounter.
Wales star James Hook kicked the Ospreys to victory with five penalties, but Leicester’s losing bonus point meant they finished top of Pool Three.
Tigers look unlikely to secure a home quarter-final tie, though, while the Ospreys can now only progress as one of two best runners-up.
If the Ospreys survive, they could face an intriguing all-Welsh clash against Cardiff Blues in April.
All the Ospreys can do is play an agonising 24-hour waiting game, but Leicester have no such worries.
Derick Hougaard’s penalty hat-trick proved sufficient to give them the point they required, as for the second time in Heineken Cup combat this season, Ospreys and Leicester played out a tryless game.
Meanwhile, Perpignan concluded their campaign with a resounding 50-16 victory over Pool Three whipping boys Treviso.
The French visitors led 24-9 by half-time and never looked like letting the Italians back into the match.
Tries from Guilhem Guirado, Nicolas Durand, Farid Sid (2), Adrien Plante, Olivier Olibeau, Christophe Manas and Jerome Porical made it another miserable day for Treviso, who finish bottom of the pool with no points.
