Exeter's defence of their Champions Cup crown has suffered a grave setback following the cancellation of Sunday's match against Toulouse because of an outbreak of coronavirus.

The Chiefs have reported a number of positive tests for Covid-19 and are unable to fulfil the round two fixture at the Stade Ernest Wallon.

The knock-on effect is that Glasgow - Exeter's opponents last weekend - are unable to field a side against Lyon due to the need for some of their players to self-isolate, meaning their game is also cancelled. 

EPCR said they will convene the Match Result Resolution Committees to determine the results of the cancelled matches.
