Under contract at Bayonne for the past two seasons, Moon, 29, was unable to agree terms on an extension with Aviron Bayonnais, where he played in a large share of the matches last season and in a handful this year despite an ankle injury.

Having identified reinforcement at lock as a priority, UBB wrapped up the deal and convinced the English player to commit for two seasons. His arrival is part of the European champions’ strategy of adding bulk to their pack and preparing for the future while remaining competitive on both fronts.
