England prop Joe Marler has tested positive for Covid and will miss Saturday's Autumn Nations Series clash against Australia.

Marler began isolating for 10 days on Monday evening after a lateral flow and PCR tests confirmed he has the virus.

The Harlequins forward played 14 minutes as a second-half replacement in the 69-3 victory over Tonga at the weekend that launched the autumn and was destined for a similar role in the second of three fixtures at Twickenham this month.
