Ireland captain Dan Sheehan faces a fitness battle ahead of the Nations Championship clash with South Africa on 21 November after sustaining a concussion during Ireland's 42-12 win over Argentina last Friday. The hooker, standing in for the injured Caelan Doris, must complete a 12-day return-to-play protocol, which puts his availability for the Springbok test in doubt. He will definitely sit out this Saturday's match against Fiji in Dublin, with Ronan Kelleher set to start in his place.

Back-rower Sean Jansen has been ruled out of the remainder of the tournament after suffering a knee injury in the second half against Argentina and has returned to Connacht. Josh van der Flier and Rob Baloucoune are both being monitored for an ankle problem and cramp respectively.

Bundee Aki, who withdrew from the Argentina squad through illness, is expected back in training on Tuesday and is in line to return for the Fiji match. Andy Farrell names his side on Thursday.
