Sam Burgess was taken straight to hospital for scans after suffering a neck injury in South Sydney Rabbitohs' dramatic 8-6 loss to St George Illawarra Dragons at the Sydney Cricket Ground on Sunday.
Burgess suffered the injury in the 58th minute after taking the ball into contact with his fellow Englishman Mike Cooper and two other Dragons defenders. The dual international lay prone for several minutes as he was treated by medical personnel before being driven off in a Medi-Cab.
Souths coach Michael Maguire said at the postmatch press conference that Burgess had experienced "a bit of tingling down through one arm" but "the doctor was pretty positive, which is good news".
Maguire said he had been told that Burgess "had all movements" and was "pretty positive" when he was loaded into an ambulance.
"He was in a bit of pain," Maguire said. "He got compressed quite heavily.
"I've been told he was in a good frame of mind, that he was in a good head space."
Cooper said after the match that the incident "was one of those you can see coming and you think it's going to hurt".
"It did [hurt]," Cooper said of the impact.
"He knocked me straight on my backside, and I was seeing stars for a good 10 seconds."
