Sydney Roosters winger Daniel Tupou has been taken to hospital amid a troubling injury toll during the NRL clash with Canberra at Suncorp Stadium.
Tupou got his head caught in an awkward tackle during the first half and lay prone while being treated for several minutes before being driven off on a medicab.
The club reportedly said he was taken to hospital as a precaution.
Star centre Latrell Mitchell sent a scare through the Roosters and NSW Origin camps after he came off with a groin injury, only to rejoin the action in the second-half.
After tearing apart the Wests Tigers with a three-try effort ranked by many as the best individual performance in recent memory, Mitchell looked in ominous early touch against the Raiders, scoring two tries.
However he pulled up lame as he crossed for his second in the 28th minute, clutching at his groin and in obvious pain.
After rejoining the action, he at times looked ginger and appeared to be having trouble running.
Skipper Boyd Corder (head knock) was also forced from the field in the first half.
