Ulster scrum half, Ruan Pienaar, suffered a twisted knee in the defeat to Ospreys in Wales on Saturday evening.
There were fears that Ruan had re-injured the same knee ligaments which kept him out of the Springboks End Of Year Tour in November, but luckily the injury is not as serious as initially thought.
A scan revealed no significant injury.
His progress will continue to be monitored however, he is expected to resume training this week.
