Leigh Halfpenny is attended to by the Wales medical staff after taking a heavy bang.
Leigh Halfpenny was discharged from hospital today following scans at University Hospital Wales.
Everyone has been so supportive and the care that I have had has been incredibly professional and second to none
The Cardiff Blues full back was taken from the pitch in the final moments of Wales' match against Australia at the Millennium Stadium yesterday complaining of neck pain.
He was immediately admitted to hospital to exclude any serious neck injury, a process which thankfully has now been concluded.
"I want to say thank you to all of the medical teams who have looked after me following my injury yesterday," said Halfpenny. "The paramedics, WRU and Millennium Stadium medical teams were outstanding. All of the staff at University Hospital Wales were also amazing.
"Everyone has been so supportive and the care that I have had has been incredibly professional and second to none. I'd also like to thank all of those who have been sending me messages of support following the injury."
Halfpenny will now undertake a period of treatment and rehabilitation to ensure that a swift return to play is undertaken.
Nearly 40 players were involved in the first Wales Under 18 training session of the season. WRU National Performance Manager Gethin Watts is excited at the potential shown by the group and expects the Regional Under 18 Championship to hone their skills even further.
