Wales star Toby Faletau is hopeful he will be able to play in the autumn internationals despite suffering a neck injury on Friday.
The Wales No 8 was stretchered off in the Dragons' against the Ospreys in the RaboDirect PRO12.
He needed 10 minutes of treatment on the pitch before being stretchered off in a neck brace and taken to hospital.
He suffered a blow to the head when he tackled Eli Walker and then caught team-mate Sam Parry on his way to the ground.
Scans have shown no major damage and Faletau tweeted: "Thank you all for your well wishes & thanks to both dragons and ospreys physios. Nothing too serious."
After the match Dr Rohit Kulkarni, the Dragons medical officer, said: "He had some pain in his neck and with anyone with a neck injury, particularly on the rugby field, you've got to take extra precautions.
"Our suspicion is that there's not much happening but we've got to be very careful, with neck injuries in particular."
