McCallan Castles, an undrafted rookie from California and UC Davis, has joined the Chargers after spending time with the Philadelphia Eagles during the summer. His signing fills the vacancy left by Blake Lynch on the practice squad, as the Chargers look to reinforce their depth, particularly with injuries affecting their linebacker corps.

McCallan Castles is currently on injured reserve, adding to the Eagles’ injury woes. His presence on the IR list contributes to a crowded situation for the team's tight end position, as they navigate roster adjustments and potential trades or waiver claims to bolster depth.
