The Senators also got a boost from the return of veteran defenseman Thomas Chabot from an upper-body injury that sidelined him for 15 of the past 16 games.
Chabot logged 26 minutes, 37 seconds of ice time – nearly five minutes more than his season average entering the game – while playing in his first action since Nov. 22. He assisted on Tkachuk’s go-ahead tally in the second period.
