Shingler: Tied to Wales

Shingler was judged by the IRB to have been "captured" by Wales after playing in an Under-20 international against France in 2011.

The eligibility row was sparked when 20-year-old Shingler, a fly-half or centre, was included in Scotland's Six Nations squad earlier this year.

The Scottish Rugby Union appealed against the original decision that Shingler was tied to Wales, made by the IRB's regulations committee.

But that appeal was thrown out at Tuesday's IRB council meeting.

An IRB statement said: "Under the regulations committee decision Shingler was deemed to have been captured by Wales, having represented the Wales Under-20 team against the France Under-20 team in a 2011 Six Nations fixture.

"Following the Scottish Rugby Union's appeal of the Shingler decision, the IRB council considered and determined the matter during its annual meeting in Dublin.

"Council, having considered all the facts and having heard submissions from the SRU and WRU legal representatives, dismissed the appeal and upheld the decision of the IRB regulations committee.

"The council therefore determined that Steven Shingler is tied to Wales in accordance with IRB regulation 8 and therefore is ineligible to represent another union."

The decisive factor was that both Wales and France had designated the Under-20s as their second senior national representative team for that match.
