Wilson, a strong and mobile No. 8 who turns 23 this September, is part of a dynamic trio that breathed new life into the Ulster back row last season and as one of Ulster's rising stars has been earmarked by many for future international glory.

Ulster Rugby Chief Executive Michael Reid said: "We are delighted to have secured Roger's talents for the next four years, indeed, this is the first time that Ulster Rugby have signed a player on a 4 year contract, and means that Roger will stay with us until after the next World Cup. A regular in the Ulster starting line-up last season he's added a hard edge to the Ulster pack and has become a key member of the squad."
