Bulls have confirmed the signing of Boom Prinsloo following his release by Cheetahs.
The 28-year-old loose forward has agreed a two-year deal with the three-time Super Rugby winners.
There were concerns over his eligibility with SANZAAR regulations limiting a player to being named in one franchise's matchday squad per campaign, but Bulls announced Prinsloo will be available with immediate effect.
"I needed a fresh challenge in my career and this is it," Prinsloo said in a statement on the Bulls website.
"I had a great time in Bloemfontein and will only have good memories about the opportunities they created for me in Free State, but I felt that it was time for change.
"Few challenges greater than making the Bulls squad come across a player's career, so I am very keen to make the best of this opportunity.
"I am very positive to learn and contribute to the squad and union and cannot wait to start."
