Seán Cronin a doubt for Champions Cup opener as Irish players return to provinces

A host of Leinster's World Cup players are expected to make a return to action against Connacht next week - but Seán Cronin is a doubt for the Champions Cup opener the following week.

Fergus McFadden, who suffered an elbow injury in training, is unlikely to make the European clash with Benetton on November 16, but the hooker has a "slightly better" chance of making it.
