Munster have been boosted for their vital Heineken Cup mission to Vicarage Road to face Saracens by the return of back-rowers Sean Dougall and Niall Ronan, while Ireland flyer Simon Zebo is also set to get the all-clear.
Tommy O'Donnell will be re-integrated to squad training towards the end of this week, though it is thought unlikely he will be in contention for a place in the squad.
Zebo (ankle) is expected to be fit as Munster seek to gain a decisive edge in qualification, while Ronan O'Gara is also reported to be showing no ill-effects from the back problem that made him a doubt for the Saracens game.
The issue arose after training last week and as a result JJ Hanrahan was called in as cover.
"Obviously, it wasn't something we wanted to advertise," a Munster spokesperson said, "but on Friday night you really couldn't see him playing."
The ERC have confirmed that Jerome Garces will referee the game, taking over from fellow Frenchman Pascal Gauzere, last Saturday's late replacement for the injured Romain Poite.
