The Tennessee Titans placed tight end Delanie Walker on Injured Reserve on Wednesday.

Walker finished out 2019 with 21 receptions for 215 yards and two touchdowns. Walker last saw action in Week 6’s shutout loss to the Denver Broncos, and has been inactive for the last four games.

Players like Jonnu Smith, MyCole Pruitt and Anthony Firkser will be called upon to step up in the pass-catcher’s place.

The team also signed kicker Ryan Santoso to the active 53-man roster, and will keep both him and Ryan Succop on the roster ahead of Sunday’s matchup against the Indianapolis Colts.

Santoso had a pair of preseason stints with the Detroit Lions, and also saw time with the Montreal Alouettes of the CFL back in September.

His specific role for the future has yet to be determined.

The Titans and Colts are set to face off at noon CT on Sunday in Lucas Oil Stadium.
