In Munster, doing an Erasmus means going away for more than a year.
Having already lost Rassie Erasmus to the Springboks, Munster have been forced to play down reports that Johann Van Graan is going to leave Munster to take up a job with the Bulls in Super Rugby.
There were reports in South Africa that Van Graan was set to return home to take up a coaching role with the Bulls, a club he is steeped in. His father is the club's CEO, and he has previously worked on the club's coaching staff.
In spite of these reports, however, the Irish Independent report that Munster have played down any speculation linking Van Graan with an early exit from Thomond Park.
Elsewhere, Munster have been beset with a series of injuries to greatly complicate the start to the season. Conor Murray remains out with a neck injury that seems likely to sideline him from the November Internationals. Elsewhere, his emergency cover Alby Mathewson is out injured too, and the latest casualty is the luckless Tommy O'Donnell, although his prognosis is better than expected having suffered ankle ligament injury, rather than a break. Rhys Marshall, Dan Goggin and Arnie Botha all picked up injuries in Saturday's win over Gloucester.
To further compound troubles: Chris Farrell still hasn't played since the Six Nations, while Jaco Taute is struggling for fitness, too.
After an unbeaten start to the Pool Stages of the Heineken Champions Cup, Munster return to league duty with Glasgow visiting Thomond Park on Saturday.
