Scarlets fly-half Sam Costelow will miss the remainder of the season after undergoing ankle surgery, dealing a significant blow to both club and country. The 25-year-old suffered the injury during Wales' Six Nations defeat against Scotland in Cardiff in February, forcing him to miss the tournament's final two games. Costelow had been recalled to start against the Scots and impressed before being forced off injured.

His absence extends to the final four games of the Scarlets' United Rugby Championship campaign, which concludes in mid-May. The Ospreys' Dan Edwards stepped in for the remainder of the Six Nations competition. Costelow's injury now puts his availability for Wales' summer fixtures in serious doubt, particularly with the uncapped international against the Barbarians at Twickenham on June 27.

Costelow faces an intensive rehabilitation period to be ready for Wales' Nations Championship campaign beginning in July. The Scarlets and Wales coaching staff will monitor his recovery closely, though his timeline remains uncertain. This setback represents a major loss for both teams, given Costelow's recent form and importance to their respective game plans.
