Former Springbok and Sharks loose forward Jean Deysel has signed a two-year contract with Ulster.
The 32-year-old, who was initially on a three-month loan at Munster from the Sharks, will arrive at his new club in mid-July ahead of the 2017-18 season.
'I'm very pleased with this outcome as I think Jean will add value to our squad on and off the pitch,' said Ulster's operations director Bryn Cunningham.
'He is one of the strongest ball-carriers in South African rugby and relishes the physical side of the game. He is abrasive and confrontational, with and without the ball, as we have witnessed first-hand for Munster.
'He has captained the Sharks a number of times and that leadership and added experience will be important for us as we look to nurture some talented young forwards in our pathway.'
