In an interview with TSN Radio 1200 on Monday, Senators general manager Pierre Dorion said that league rules prevented the NHL club from making the roster move.

"The exact rule is, we had eight defencemen on our roster at the trade deadline," Dorion said. "So, we would need four injuries to fall into an emergency status, in your second emergency status, then at that point in time, you can recall Thomas Chabot... When it comes to these things we always look at every possibility and everyone that's under contract that could come and help us.
"In theory, when we look at it, one of our other guys would have to go down, then we'd have four healthy bodies and we'd be in second emergency, then we call up Thomas Chabot. I don't think the Saint John Sea Dogs would like it a lot."
Dorion went on to call Chabot arguably the best defenceman currently outside the NHL.
Chabot started the year with the Senators, playing in one game.
The 20-year-old recorded 10 goals and 45 points in 34 games with Saint John during the regular season. He is currently tied for the league lead in playoff scoring with three goals and 10 points in just four games.
