Caleb Montgomery joined Warriors in the summer of 2019 from Pro-14 side Ulster on an initial one-year contract.
Montgomery played for Warriors in the Premiership Rugby Sevens at Northampton in September 2019 and made a successful debut in the Premiership Rugby Cup match against Leicester Tigers the following week which he celebrated with his maiden try.
But a wrist injury, which required surgery, then ruled Montgomery out for three months of the season. Montgomery signed a two-year contract extension in January 2020.
The talented back-row forward made his senior debut for Ulster as a replacement in their Pro-14 match against Leinster in January 2019 and was a regular in their A team during the 2018/19 season.
He was part of the Ulster A team that took part in the Cara Cup tournament in the United States in March 2019.
Portadown-born played club rugby for Banbridge in the All Ireland League during his time with Ulster.
