Backes believes he could be ready to play as early as Sunday night against the Montreal Canadiens, but understands the decision will ultimately lie with Bruins head coach Bruce Cassidy, who termed Backes as "very close" to a return following Saturday's practice.
"The team was extremely supportive, and I've been given a clean bill of health," said Backes. "You know my history as far as if I'm playing when I'm at full health or not. I'm hopefully going to be available as soon as [Sunday] and then it would be up to the powers that be whether 42 can slot into the game to help us win another one."
The Minnesota native resumed on-ice activities with skating and skills coach Kim Brandvold last week after receiving some positive - and what he describes as better-than-expected - news from multiple doctors, including an independent, out-of-state neurologist who assured Backes that he should not be concerned about his health upon his return to the ice.
"Multiple neurologists have told me there's no reason for me to be hesitant, to worry about more contact, more hits because you're doing fine," said Backes, who did not divulge the extent of his injury, other than to say there were "certainly some concussion-like symptoms" following the hit.
"From that, I'm excited to be back with a clean mind, not thinking that my next hit could be something that ends my career. That's something that's been on my mind and to not have that, I'm hoping to be freer and able to play a freer game out there."
Given his concussion history, as well as the image of Sabourin fresh in his mind, Backes acknowledged the difficulty he had processing the incident. Backes reached out to Sabourin and stayed in touch with the Senators rookie - who suffered a fractured nose - in the aftermath of the hit and said he continues to pray for his full recovery.
"If that's my wife and my parents, and my kids seeing that - I didn't know Scott from anybody in the world really before that incident, but he's got a fiancée, found out his parents were watching, hometown Ottawa kid," said Backes. "That's got to be extremely scary for all those people. At the same time, [I'm] worried about my own health with a long history of hits like that."
It was for those reasons, that Backes opted to take a step back and engage in a thorough review of his neurological well-being by doctors that specialize in hockey-related head injuries.
"Having full workups done by them, [asking], 'Am I'm damaged and broken? Is there a point I should stop playing this game, or can you tell me that I'm healthy and that my brain's healthy?' The short term and returning to play is certainly a decision to be made, but I've got kids and I'm hopefully gonna live another 50 years after I'm done playing. That's a concern as well.
"I'm a human, so those are thoughts and questions that I wanted answers [to] before I put my skates back on and I put myself back into these games. I got all those answered with, truthfully, better answers than I thought I was gonna get with the history that I have."
