Ireland's Jansen ruled out of Fiji and Bok games

Sean Jansen has been ruled out of the remainder of Ireland's Nations Championship campaign with a knee injury, further depleting head coach Andy Farrell's options at number eight.

With Caelan Doris and Jack Conan already injured, Jansen was forced off during Friday's 42-12 win over Argentina in Dublin and will return to Connacht to continue his rehabilitation.

Hooker Dan Sheehan will miss Saturday's home match with Fiji (20:10 GMT) after sustaining a concussion against the Pumas, but the coaching staff are "hopeful" wing Rob Baloucoune (cramp) and flanker Josh van der Flier (ankle) will be available.

Sheehan - squad captain in Doris' absence - is a doubt for the South Africa game on 21 November as he undergoes 12-day return-to-play protocols.
