Premiership club Worcester Warriors have signed Ulster back row Caleb Montgomery from the end of this season.
The 23-year-old made his senior debut for the provincial side in January.
"I am hugely excited. It is a great club with passionate fans, excellent facilities and a strong, talented squad that really play for each other," Montgomery told Worcester's website.
"I can see the honest and fair environment [director of rugby] Alan Solomons has created at Worcester."
