Back in action.

Munster have been handed a significant boost ahead of their Champions Cup opener this weekend away to Castres, with news that lock Jean Kleyn and Ireland international Simon Zebo should be fit.

South African second-row Kleyn, who has had an excellent start to the season, has been troubled by a neck injury recently. But he is expected to train fully this week and will be available for selection.

“[Jean is] looking on track so hopefully he’s ready. Simon [Zebo] should also be available this week,” Erasmus told RTÉ Sport. 

The southern province reached the semi-final of the Champions Cup last season, but know improvement is needed after their loss to Leinster at the Aviva over the weekend.
