When one British and Irish Lions Test full back is injured, Wales are blessed another one can slot directly in.
Leigh half-penny looks set to miss out the Six Nations opener against France on 1 February, after being eliminated for a further three to four weeks with a concussion injury he suffered on 10 November.
Half penny has been the 2013 Lions man of this series from Australia, but step forward Liam Williams – the 2017 Lions full back in three Tests against New Zealand, and now favourite to wear the exact Wales 15 jersey at Paris.
There are other choices for head coach Warren Gatland at Jonah Holmes, Hallam Amos and Gareth Anscombe, but Williams is the man in possession after starting at full back against South Africa – the last of Wales’ four fall Test victories.
That came just a week after playing the wing along with scoring two tries against Tonga on his 50th cap.
“I’ll play anywhere, so exactly what is going to be will be,” said the 27-year-old.
“I really don’t pick teams so we are going to need to wait and watch. There exists a good deal of rivalry [from the trunk three] which is healthy leading up to this worldcup.
“The fall internationals success put us in good stead for the Nations.”
Modesty from the man himself, but Saracens club coach Mark McCall thinks he are the perfect replacement, even though McCall plays Williams primarily on the wing together with Alex Goode in full back.
“Any game Liam has played over the last 18 months in full-back he was well – great actually,” said McCall.
“He’s Test experience there and would be a pretty good replacement for Leigh if he can’t create it.
“Liam is among the very competitive and committed players I’ve come across, along with some worldclass abilities, specially in the air.”
