Wales and Newport Gwent Dragons number eight Toby Faletau has been discharged from hospital after being stretchered off on Friday.
The 22-year-old Lions number eight was forced to leave the field in a neck brace after attempting to tackle Ospreys winger Eli Walker, and taken to hospital after complaining of numbness in his left arm.
Following an X-ray, Faletau was discharged after the results showed no major damage.
"Thank you all for your well wishes & thanks to both dragons and ospreys physios. Nothing too serious," said Faletau in a tweet.
"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," Dragons' medical officer Rohit Kulkarni told WalesOnline.
"Our suspicion is there's not much happening but we've got to be very careful, with neck injuries in particular."
Wales will be concerned over Faletau's progress in the coming days, having already lost Jamie Roberts and Alex Cuthbert to injury ahead of the November Internationals.
