England winger Anthony Watson has reportedly suffered a jaw injury in training.
The Bath player is the second member of the training camp in Brighton to have picked up an injury after Sam Jones broke his leg in a judo session.
According to BBC Sport, Watson is believed to have fractured his jaw, which puts him in doubt for Autumn Internationals against South Africa, Fiji, Argentina and Australia.
England's opening match will be against the Springboks on November 12 at Twickenham.
