Andrew Kitchener joined the Warriors Academy in 2014 and is the younger brother of former Warriors lock Graham Kitchener.
The giant second row was handed his first-team debut in Moscow against Enisei-STM in the European Challenge Cup in October 2016.
Kitchener continued to impress when handed the opportunity and went on to make 12 appearances across the 2016/17 campaign, as he featured in every European Challenge Cup fixture, while also making his Premiership debut against Northampton Saints in November 2016.
The lock also featured for Worcester Cavaliers from 2013 to 2017 and has recently combined his rugby with studying at Birmingham University.
In 2016, Kitchener was called up to England Under 20s' squad for the Six Nations and then helped them win the World Rugby Under 20 Championship in June alongside Warriors teammates Huw Taylor and Jack Singleton
