Burmistrov has produced one goal and eight assists in 19 games for the Coyotes, who claimed him off waivers in January.
• Boston won, 4-1, to stretch its winning streak over the Coyotes to 10 games. Arizona's last defeat of the Bruins occurred on Oct. 9, 2010 in Prague, Czech Republic.
"Just too many puck mistakes by key players," Tippett said. "(Alex) Goligoski, (Oliver) Ekman-Larsson, you can't have that. I understand where we're at and everything, but there's a pride that you have to play with and there wasn't enough of that tonight."
Tippett said some roster moves are likely to come soon after the NHL trade deadline passes at 1 p.m. Arizona time on Wednesday.
"We'll see how tomorrow goes," Tippett said. "We've got some young players here that are going to have to go and play in the minors ... We'll get our lineup figured out after tomorrow."
• Forward Radim Vrbata assisted on Peter Holland's power-play goal at 3:27 of the second period to extend his point streak to 10 games. The longest point streak in the history of the Coyotes is 11 games set by Jeremy Roenick in 1999 and Shane Doan in 2008.
• Goalie Mike Smith stopped only 10 of 14 shots in the first two periods and did not play in the third period.
"I'm in a little funk right now and I need to find a way to get out of it," said Smith, who missed the past two games because of illness. "I'll get to work in practice and start playing like I'm capable of playing."
Smith was asked if watching Burmistrov get carried off the ice affected his performance.
"When the signal gets made and the paramedics come on the ice, it's always hard to deal with, but that's no excuse, for sure," Smith said.
