As soon as he was cleared by doctors, Backes went to the Bruins practice facility to ride the bike and break a sweat. He has skated for the past four days, but isn't sure when he'll be back in the lineup.
"So to pick up from not sweating for six, seven days to get back, to be on the ice, to feeling the way I feel today ... I got a little work in while the guys were away, so progress certainly," he said. "Return? We'll see."
Backes said doctors were uncertain of the cause of his illness, and it's something he'll have to monitor.
"Trying to gather information and be as smart as I can," he said, "so that I am available as often as possible and as productive as possible."
Bergeron skated on his own for 10 minutes before practice Tuesday and then joined his teammates. Though the color of his jersey meant no contact, he definitely came into contact with teammates several times during drills. He left practice before the Bruins began 3-on-3 drills down low.
"Today was one of those where I wanted to see where I was at," Bergeron said. "We felt like were comfortable with doing drills and being with the team. Didn't necessarily know what kind of practice [Cassidy] had for us. So I went along and felt good, so kept going."
Bergeron said he's feeling stronger and more comfortable, and expects to be able to dress for a game soon.
The Bruins had no update on forward Ryan Spooner (lower body) or defenseman Adam McQuaid (lower body), who left early during Boston's 3-1 loss to the Vegas Golden Knights on Sunday.
