The Prix du Prince d'Orange at Longchamp was marred by the death of Paul Cole's River Proud.
Oliver Peslier had cut out much of the running on the three-year-old but he was struggling in the straight and tragically collapsed and died.
Never On Sunday claimed the Group Three heat for Jean-Claude Rouget, with Russian Cross second.
Mick Channon's Canwinn was also in action in the Group Three Prix des Chenes, finishing third behind Calvados Blues under Peslier.
