Colts add Darius Slayton while Micheal Clemons moves to injured reserve

Indianapolis signed free-agent receiver Darius Slayton and placed defensive end Micheal Clemons on injured reserve Tuesday. The Colts also released running back Anderson Castle from the practice squad. It is a three-part roster move with a clear RSO split: Slayton gives Anthony Richardson another downfield option, while Clemons' absence changes the defensive rotation.

Slayton arrives after seven seasons with the Giants, 106 games and 4,435 career receiving yards. He had 37 catches for 538 yards and a touchdown in 2025. The Colts' official player page lists him as signed on Sept. 22, and the club's transaction release says he joins a receiver room that recently lost Alec Pierce to a heel injury expected to cost several weeks. Slayton is therefore a more direct waiver consideration than a generic practice-squad addition, though his exact snap share is not announced.

Clemons has appeared in two games for Indianapolis this season. The official release lists 67 career games, 24 starts and 8.5 sacks, combining his Colts and Jets work. His move to IR takes away a rotational edge presence, but Indianapolis has not published a replacement plan. Managers in IDP leagues should wait for practice participation and game packages before elevating a backup.

Castle's release matters mainly for the running-back depth chart. He was an undrafted rookie with 308 college carries for 1,524 yards and 20 touchdowns, but he had not established a role on the Colts' active roster. The move does not change Jonathan Taylor's workload by itself.

Slayton's arrival is the usable fantasy signal. He brings speed and experience to a Colts passing game that needs a second perimeter threat, but a contract or signing does not guarantee immediate volume. RSO managers should add him where receiver depth is thin, then watch his first practice report and route participation. The defense side remains a monitoring story until Indianapolis identifies Clemons' replacement.
