Chiarot suffered an upper-body injury during Saturday's 5-1 loss to Montreal, per Helene St. James of the Detroit Free Press.
Chiarot was limited to 13:48 of ice time and missed the third period due to the injury. No update arrived on his status during the post-game press conference, so it's unclear if he'll be an option for Monday's tilt against St. Louis. If Chiarot can't play, Albert Johansson would probably draw into the lineup.
