Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
The 26-year-old lock was replaced by Billy Holland in the 12th minute, quickly followed by out-half Paul Warwick and flanker Niall Ronan as Munster's bad run of luck with injuries continued.
Warwick (dead leg) is expected to be available for Munster's next Magners League game against the Newport Gwent Dragons on Saturday week.
But Ronan, who, like Ryan, sustained a shoulder injury, will need to wait until further medical examination before the full extent of his injury is known.
