London - Bath wing Anthony Watson is likely to miss England's forthcoming internationals after suffering a broken jaw.
Watson's injury came during England's three-day training camp in Brighton this week and Bath director of rugby Todd Blackadder expects him to be out of action for a lengthy period.
"It's too early for a full medical prognosis on how long he'll be out for, but it's likely he'll miss the autumn internationals," Blackadder said on Thursday.
The painful blow came 24 hours after it was revealed Wasps flank Sam Jones fractured his right leg while doing judo while on training duty with England.
Watson's absence will deprive England of one of their main weapons when they face South Africa, Fiji, Argentina and Australia in a series of Test at Twickenham beginning in November.
The 22-year-old has amassed 12 tries in 24 Tests and was a certain starter on the wing, fitness permitting.
"Anthony's in great hands with our medical team and we look forward to seeing him back on the pitch when he's ready," Blackadder said.
Watson's Bath colleague Semesa Rokoduguni is favourite to fill the void on the right wing with Jack Nowell operating on the left.
England flank James Haskell, back row Jack Clifford and centre Manu Tuilagi had already been ruled out through injury, while uncertainty shrouds the back problems incurred by Owen Farrell and Dylan Hartley with dates for their return yet to be set.
