Gloucester have confirmed the signing of Munster second-row Gerbrandt Grobler for next season.
The South African, who served a two-year suspension for the use of steroids before coming to Europe, spent a controversial year at Thomond Park in which he made 11 appearances for the senior team.
At Kingsholm he will link up with head coach Johan Ackermann who himself served a ban for the use of performance-enhancing drugs during his playing career.
Grobler was only ever expected to remain at the Irish province for one season as he bridged the gap between departing lock Donnacha Ryan and incoming Scarlets tyro Tadhg Beirne.
Meanwhile, Jack O'Donoghue will this week meet a specialist to discover how serious the knee injury he suffered in Saturday's PRO14 semi-final loss to Leinster is. The flanker is expected to be ruled out of Ireland's summer tour.
Second-row Jean Kleyn will have scheduled surgery on his ankle, while hooker Rhys Marshall will have an operation on his shoulder.
Munster believe JJ Hanrahan's hip problem is not serious.
