The Bulls have bolstered their squad with the acquisition of former Sharks loose forward Renaldo Bothma.Bulls coach Nollis Marais was beaming yesterday, not just because his charges deprived the Sharks victory in their 16-16 draw last Friday, but because he was chuffed with having brought the 26-year-old Namibian international to Loftus Versfeld."He is a guy with a fair bit of experience. I think he's a really good ball-carrier," said Marais.The 1.90m, 105kg loose forward will not walk into the team.He has just recovered from a foot injury and spent yesterday undergoing medical tests while his new teammates sweated it out preparing for their first overseas trip (Singapore to play the Sunwolves) of the season."He's undergoing medicals this week. We will wait for the medical clearance first and see from there how it goes. He will definitely be a valuable addition to the squad," said Marais."We just want to make sure he gets used to our system first. We also have Steggies [Deon Stegmann] and Lappies [Labuschagne] making their returns [from injury] next week. That will make a huge difference. It's good because I want to have those interesting and difficult selection posers."The Bulls will leave later today for Singapore, where they expect a tough encounter with the Japanese newbies to Super rugby.The side from Pretoria is also expecting some tough conditions, like the humidity the Cheetahs experienced last week...
