The Seahawks made a trio of transactions on Tuesday, as a result of an unplanned move. Ethan Pocic, who just came off injured reserve on December 14, will go back onto I.R. with a core injury, per the Seattle Times’ Bob Condotta:
Seahawks today signed guard Kyle Fuller from the practice squad to its 53-man roster and put Ethan Pocic on Injured Reserve. Pocic missed 49ers game with a core muscle injury.

As Bob notes, guard/center Kyle Fuller has been promoted from Seattle’s practice squad to take his place.
