Ottawa Senators winger Tom Pyatt is listed as out day-to-day with an upper-body injury, according to Bruce Garrioch of The Ottawa Citizen.
The 30-year-old yard left Game 4 against the Boston Bruins Wednesday night when he was hit by defenceman Kevan Miller in the first period.
Pyatt scored nine goals and added 14 assists over 82 games with the Sens in 2016-17, his first in the nation's capital. He's played in all four postseason games this year.
The Sens lead their opening round series 3-1 over the Bruins. Game 5 goes Friday night from Ottawa.
