Doak, Hefferman added to injury-hit Ireland squad in South Africa
Scrum-half Nathan Doak and hooker Dave Heffernan have joined an injury-hit Ireland squad ahead of the second Test against South Africa, the national rugby union confirmed on Tuesday.
An Irish Rugby Football Union statement said "Connacht hooker Dave Heffernan and Ulster scrum-half Nathan Doak have been called up and the duo have linked up with the squad in Durban".
The players flew to the Indian Ocean city, venue for the international on Saturday, after scrum-half Craig Casey and hooker Dan Sheehan were ruled out by injuries sustained in the first Test.
Sheehan could be sidelined for up to nine months by a left knee injury during the 27-20 loss to the world champion Springboks in Pretoria last Saturday.
Casey is recovering from concussion after being tackled by South Africa lock RG Snyman, who will play for Leinster next season after being a teammate of Casey at Munster.
Heffernan has been capped seven times by Ireland and joins likely starter Ronan Kelleher and Rob Herring as the hooker options for head coach Andy Farrell.
