“Gareth is a big strong man who will provide us with another good option and enhance competition for places in the front row. We have been aware of his development since his move to Worcester and we’re looking forward to seeing him contribute to Ulster from next season.”
Warriors Director of Rugby Alan Solomons said: “Gareth has made a valuable contribution to the team during his time here at Sixways.
“Although we are sorry to see him go, we appreciate that his move to Ulster affords him the opportunity to challenge for international honours. We wish him all the very best.”
