Bulls lock Grant Hattingh will miss their Round Five Super Rugby clash with the Sunwolves in Singapore after suffering a groin injury on Monday.
Hattingh injuried his groin during the team’s final training session before departure on Monday and was immediately sent for medical treatment.
The 25-year-old's place in the Bulls touring squad will be taken by Nicolaas Janse van Rensburg, who could feature in his first Super Rugby encounter this year after making his debut in 2015.
Meanwhile, loose forward Renaldo Bothma is undergoing medical assessments on his foot injury and is expected to resume training when the team arrive from Singapore next week.
Head coach Nollis Marais is eager for the new recruit to get settled in the Bulls set-up and is particularly looking forward to him using his ability to get over the gain line.
“He has a lot of experience and is someone who I think is a very good ball carrier," Marais told Supersport.
"Obviously he is doing medicals this week as he is coming back from a foot injury. We will see how it goes, we will get all the necessary medical clearances and all that but I think he will be a valuable addition to our squad."
Flankers Lappies Labuschagne and Deon Stegmann are also set to return from injury while prop Dean Greyling is also expected to be fit.
“Ja, we need to make sure he gets into the system first, and see how it goes," added Marais.
"We also have Steggies and Lappies making their return next week. With three senior guys coming back it is likely to make a huge difference, but he has to get used to our conditions and how we do things. But as we are an advantage team, I think he will make a huge impact."
Marais said he is looking forward to his impending back row selection dilemma where Arno Botha, Roelof Smit, Nic de Jager, Hanro Liebenberg and Jannes Kirsten have all put their hands up to be picked.
“That’s good,” added Marais with a smile.
“I want interesting selection dilemmas and that’s the thing. We’ve always said we want to strengthen how the Bulls want to be in the next four years and I’m not only looking this season but also for the future and I’m looking to build.”
