Dan Biggar's participation in the remainder of the Rugby World Cup could be in doubt after a sickening collision with team-mate Liam Williams in the second-half of their Pool D clash with Fiji in Oita.
The Northampton Saints outside-half lay motionless on the turf after taking an horrific blow to the head in a horrible collision with Saracens star Williams in the 56th minute.
It sparked immediate concern from team-mates who were quick to comfort him.
After some treatment from the medical team, Biggar was able to stand jog off the pitch to be replaced by Rhys Patchell to a rousing ovation from the Welsh fans.
But it's the second head injury Biggar has suffered in the tournament, having gone off in the decisive Pool D win over Australia.
Biggar is now bound to be a major concern for the knockout stages.
It would be a massive blow for Wales having already seen Gareth Anscombe fail to make the flight to the Far East over a serious knee injury.
It would leave Wales down to just one fit No.10 in Patchell among Warren Gatland's squad.
