The Bruins’ center depth took a hit on Saturday afternoon.
Boston’s top-line pivot Pavel Zacha played just 6:42 of ice time against the Coyotes on Saturday, with the 26-year-old forward ruled out after the first period of play due to an upper-body injury.
Following Boston’s eventual 5-3 win at TD Garden, Jim Montgomery did not have a definitive timeline on how long the top-six forward is expected to be out.
“I’ll have more Monday,” Montgomery noted. “I just know it’s upper body. I haven’t seen him yet and talked to the doctors.”
It’s unclear how Zacha was injured against Arizona, with the forward anchoring a top line between Brad Marchand and David Pastrnak over the first 20 minutes of regulation on Saturday.
