Murray, Earls back for Munster
Munster new boy Jaco Taute will not make his debut this weekend despite training with the squad for the first time in yesterday but Conor Murray and Keith Earls will return.
Out-half Tyler Bleyendaal is also expected to be in the mix for Saturday's trip to face Dragons.
It was confirmed that Tommy O'Donnell sustained a concussion in last Friday's defeat to Cardiff Blues, with the flanker currently following return to play protocols.
Rory Scannell's neck injury was not as bad as first feared but the news may not be as positive for lock Dave Foley who sustained an elbow injury. After undergoing a scan the lock requires further consultation with the specialist.
The injury crisis at hooker has opened the door for ex-Melbourne Rebels and Leinster player Tom Sexton to link up on a trial basis.
Connacht also have their injury headaches with winger Danie Poolman was the latest to suffer from concussion last weekend and he is going through the return to play protocols this week. Peter Robb is still unavailable after he took a knock against Glasgow.
The Six Nations will not be moved from its current spring slot under proposals to introduce a more aligned global rugby calendar from 2020.
However, summer tours in World Cup years will be scrapped while the Pro12 and Premiership will start later and finish in June to coincide with the end of the Super Rugby season down south.
