Castrin is dealing with pubalgia during Sevilla's start to preseason, according to Edu Sanina of Zona Mixta.
Analysis:Castrin was one of Sevilla's breakout performers during the final stretch of last season, and the club will be cautious with his workload given how difficult pubalgia can be to manage if pushed too quickly. The issue is considered one of the more persistent and tricky injuries to treat, so Sevilla is likely to ease him back gradually rather than risk aggravating it further. His recovery timeline through preseason will be worth monitoring as the club looks to have him ready for the start of the new campaign.
