New Ulster signing Duane Vermeulen arrived in Belfast on Monday and forwards coach Roddy Grant can't wait to work with the Springboks star.

The powerful number 8 was due to play with the Barbarians against Samoa in London on Saturday but that game was cancelled just before kick-off due to positive Covid-19 cases in the camp.

Dan McFarland announced the signing of the 35-year-old in September but the former Bulls man was on duty with South Africa for the Rugby Championship and the Autumn Nations Series.

"I'm not sure about availability, he’s arrived," confirmed forwards coach Roddy Grant when asked about when he would be cleared for action.

"He’s in Belfast and going through the protocols of coming in. There are a few things to that. We’re just getting through it today, we’ll see how we go."

Vermeulen was man of the match in South Africa's World Cup final win over England

Ulster, who beat Leinster at the RDS for the first time since 2013 on Saturday night, face Ospreys on Saturday.

"It's very exciting obviously," added Grant of the 6'4" former Toulon player, who has 61 international caps.

"It was announced a while ago but it’s like Christmas, when it comes it’s exciting, certainly for me as a forwards coach.

"There are multiple layers of this. Guys say he’s a brilliant bloke a great leader, obviously has a huge presence.

"Young guys will pick up that, how he carries himself, how he talks, how he plays, he’s so consistent, he’s got massive plays.

"It’s sort of like modelling behaviours.

"For me, he is the best mauler in the world, you’ve got Will Skelton, Uini Atonio who are also some of the best, but I think he’s the best.

"To have him come into our maul is really exciting.

"He’s generally a world class player. It’s a pleasure to coach that."
