The Bruins needed to clear a spot on their 23-man roster to make room for the return of winger Brad Marchand from injured reserve. So despite his share of the team lead in goals with five, Seth Griffith was assigned to Providence of the American Hockey League on Monday afternoon.

Marchand, who missed the past three games with an undisclosed injury, took the morning skate with the Bruins. He also has five goals this season and should be back on a line with Patrice Bergeron and Reilly Smith when the Bruins host the Pittsburgh Penguins on Monday at 7 p.m.

Griffith did not require waivers to be assigned to Providence. So that was the easiest move for Boston to make at this time. The Bruins don’t play again until Friday, so it’s possible Griffith could return without even playing for Providence, which doesn’t play until the weekend.

Although Griffith has been one of the Bruins’ top goal scorers, he ranks just above Gregory Campbell, Daniel Paille and Simon Gagne in terms of average ice time by regular forwards. He also has 25 shots in 18 games. He was a regular on the power play but didn’t kill penalties.

Forward David Pastrnak and Jordan Caron were both recalled from Providence on Sunday. They were not designated as emergency call-ups.

Pastrnak might replace Griffith on the power play.
