Munster are hoping to have their talismanic flanker Peter O'Mahony fit for this weekend's Pro12 semi-final with the Ospreys.
The Ireland star and Munster captain picked up a hip injury during training last week.
O'Mahony is now being put through his paces by the Munster physios in a bid to be available for Saturday's big game at Thomond Park.
Munster head coach Anthony Foley however was cautious when speaking to the media on Tuesday, revealing that O'Mahony wouldn't be rushed back unless he was fully fit.
"It's hard, judging by the character of the fella that we all know," Foley told reporters.
"He just wants to feel pain-free and if he feels pain-free he will kick on and he can go through a lot.
"He is the captain of the side and we all want him to get there. But if it is not right for him to get there he will not be taking the field.
"We will give him every opportunity to get in for the semi-final because he is a big player.
"It's more running and making sure that he is comfortable doing that before we engage him any further in scrummaging or wrestling or anything on Thursday to see if he is fully fit."
