Bruins forward Zac Rinaldo has had many run-ins -- with opposing players during his four previous seasons with the Flyers and with the NHL's department of player safety. Rinaldo narrowly avoided a suspension for his hit on former teammate Sean Couturier on Wednesday, a shot that knocked Couturier from the game and drew a major and game misconduct for Rinaldo.

But Rinaldo was not suspended or fined, so he was in the lineup Friday night to face the Islanders. They know Rinaldo well. John Tavares and Casey Cizikas both played with Rinaldo in junior hockey.

"You just have to be aware, be prepared, I guess," Cal Clutterbuck said. "There's not much else you can do. You can't really control what he's going to try to do."

Rinaldo reportedly met with NHL player safety chief Stephane Quintal last week as a pre-emptive measure. "There was a little relief finding out [Thursday] I wasn't suspended," Rinaldo said. "I'm going to stay within the rules."

Who's next in goal?Jaroslav Halak made his third consecutive start Friday night, with J-F Berube dressed as the backup. Jack Capuano gave no indication before the game what he would do with the second half of back-to-back games Saturday night in St. Louis against the Blues.

It seemed unlikely that Halak, who's been active only for a week after nursing an upper-body injury for several weeks, would go on consecutive nights. Thomas Greiss would seem the choice to start in St. Louis. Greiss went 2-0-1 in the Isles' first three games with Halak sidelined.

The Bruins went with backup Jonas Gustavsson. Tuukka Rask, the 2014 Vezina Trophy winner, hasn't been sharp to start the season. His 5-4 overtime loss to the Flyers on Wednesday night dropped him to an .854 save percentage and 4.40 goals-against average.
