Eagles centre-back Ryan Inniss has completed a deadline day move to Southend United on a season long loan.
Recently recovered from injury, the 21-year-old has played twice for the development side this campaign as he continues his quest for fitness, and will now get the chance to do so in League One where he featured 15 times on loan for Port Vale last season.
It will be the seventh loan move of his career, which has seen him gain experience at Cheltenham Town, Luton Town, Gillingham and Yeovil Town before spending time at Vale in both of the previous two campaigns.
