The Ottawa Senators are calling upon forward Chris Kelly to replace the injured Tom Pyatt Friday night as they look to close out the Boston Bruins in the nation's capital. 

The 30-year-old Pyatt left Game 4 against the Bruins Wednesday night with an upper-body injury when he was hit by defenceman Kevan Miller in the first period. 

Kelly, 36, played all 82 regular season games with the Sens this season, before being named a healthy scratch for the first four games of the playoffs. He scored five times and added seven helpers in 2016-17. 

On Boston's side of things, head coach Bruce Cassidy announced that forward Sean Kuraly will take Ryan Spooner's spot on the fourth line for Friday's game.

The 24-year-old Kuraly played eight regular season games this year with the Bruins, notching a single assist. This will be his third game of the playoffs. 

Spooner, 25, had 11 goals and 28 assists over 78 games in 2016-17 and he's added two helpers over four games in this series.

Ottawa can move on to the second-round of the playoffs for the first time since 2013 with a win tonight.
