The Predators said Monday that center Ryan Johansen is "day-to-day with an upper-body injury." Johansen exited Saturday's victory against the Anaheim Ducks near the end of the second period. He collided with teammate Kevin Fiala at center ice before leaving for the dressing room. Johansen didn't participate in Monday's morning skate and appears doubtful to play against the Boston Bruins at Bridgestone Arena.
