Earls now faces an anxious wait to find out the extent of an ankle injury, with the new Magners League season just a week-and-a-half away.
Munster have confirmed that the centre cum full back cum wing has not suffered a break, however, much to the relief of head coach Tony McGahan and Ireland boss Declan Kidney.
But while that assessment is clearly good news, the 22-year-old could still be sidelined after it was revealed that he will need to undergo further medical examination in the coming days.
"The injury occurred in a non-contact situation and a subsequent x ray revealed no break," said a Munster statement.
"However, Earls will need to undergo further medical examination later in the week to determine the exact extent of the damage."
Munster begin the new season at home to Magners League newcomers Aironi Rugby on Friday September 3, before travelling to Edinburgh and then hosting champions the Ospreys in weeks two and three respectively.
The Irish giants are already without Club captain Paul O'Connell, with the second row nursing a groin injury that he says will keep him out until December.
