But after seeking advice from specialists Halfpenny, it appears, will be back fighting fit in time for Wales opening clash of the 2013 RBS 6 Nations at the start of February against Ireland.

"We've had a few opinions now from the specialists and it seems to be about six weeks will be the time where the nerve will have settled down and it'll be safe to go back to play," the Cardiff Blues fullback told Sport Wales.

“Basically it's when my symptoms subside and I'm not in any pain or when I'm doing contact I'm not getting any pins and needles down my arms.

“At the time I wasn't sure whether Australia had scored or not. I was conscious so I was aware of the atmosphere and the crowd so I guessed that they might have scored but I wasn't sure if we had won or lost at the time.

"My head was in the ground so I couldn't see anything either. It wasn't until I got into the medical room where they were assessing me, I asked did we win or lose and they told me that they had won.

“It was devastating. That was the fourth time we have come so close now but still so far away. It's so frustrating as well."
