Castleford Tigers have released back-row forward Charlie Martin.
The 22-year-old chalked up six appearances for the Tigers since making his debut at St Helens last Easter and has spent time on loan with Championship neighbours Featherstone.
Castleford coach Daryl Powell said: "Charlie's first-team opportunities with us have been limited given the strong competition for places that we have.
"He has had an opportunity to play regular Championship rugby league and we wanted to give him the chance to do that. We wish him all the best for the future."
