Jonathan Sexton injury the only dark cloud on Leinster horizon

Seven tries to one. A 27-point differential. This Pool 1 Heineken Champions Cup encounter turned into a rout but Leinster were just three points to the good when Jonathan Sexton went down in the tackle four minutes after half-time.

Northampton head coach Chris Boyd would say later that he had seen the writing on the wall for his lads even before the interval but this was very much a going — and entertaining — concern when the Leinster skipper buckled in pain.
