Kiran joined the Falcons in the summer of 2023. The lock-forward played more than 50 games for Glasgow Warriors before moving to Wasps in the summer of 2022.

Called up by Scotland for their summer tour in 2021 only to see all three games cancelled due to Covid, he started all four games for Wasps in September 2022 before the club were expelled from the Premiership due to financial issues.

Touring with the Barbarians that autumn, he joined Munster on a short-term deal and was part of the starting XV for the Irish province when they beat world champions South Africa in front of a 50,000 sell-out crowd.
