Chabot (hand) was placed on injured reserve Thursday, per CapFriendly.
EDGE Analysis
Chabot has been ruled out for the remainder of the season, so his placement on injured reserve frees up a roster spot. He could still move to long-term IR later, though the Senators are not pushing close to the salary cap and would have virtually no benefit to make such a move. He's expected to be ready to play next season.
