The game was held up for almost 10 minutes after the incident.
Munster flanker Jack O'Donoghue will be brought for medical checks after a flying shoulder knocked him out during his side's Guinness PRO12 match against Edinburgh at Thomond Park.
The 22-year-old, who has enjoyed a positive start to the season, was at a ruck in his own half when Fraser McKenzie charged in, intent on clearing him out.
It is doubtful that McKenzie, who was sin-binned for the incident, meant to harm the former Ireland U20 captain but his actions were reckless.

Munster technical coach Felix Jones was asked about the flash-point by
Sky Sports. He replied:
"I don't know, to be honest," he said. "Jack, hopefully will be alright. I'm waiting on word on that."
Medics and Munster staff attended O'Donoghue for several minutes before he was stetchered off on a motorised cart.
We will bring you news on O'Donoghue when we have it.
