Always marked out as a teenage player of quality in 2014, while at Wallace High School, he was voted Dankse Bank Ulster Schools Player of the Year. The wing has represented Ireland Under 20s, and made his debut for the senior Ulster side as an 18-year-old in 2014. A graduate of the Hughes Insurance Ulster Rugby Academy and Ulster A team, Jacob has firmly established himself in the senior squad and is justifiably in a star-laden pool of backs. His forceful running and eye for the try-line seem to a guarantee a long future in Ulster and Ireland jerseys.
