Bergeron needed two weeks off following the PRP shot, which - during what was already a shortened summer - set back some of his training. The 34-year-old, however, does not believe his 16th NHL season will be hampered.
"I should be able to play through that," said Bergeron. "It's been there for a long time. I think with the PRP shot, it's one of those things that it takes a little bit of time to work and have its effect. It's getting better, but it's still there a little bit.
"But I'm feeling good. I'm feeling positive that I'll be ready definitely for the start of the season. That's not even an issue."
When it comes to overcoming the Bruins' Game 7 loss to the St. Louis Blues, Bergeron said the team's veteran core will draw on its previous experiences with difficult losses and short offseasons.
"I think that's what the team is gonna do, manage workload," said Bergeron. "That's what I've seen in the past, based on experience in 2013 and 2011. I know it's something that's been talked about…obviously it stings, but at the same time, you play the game because you love it, because it's your passion.
"Right now, I'm looking forward. It's one of those things where I'm just happy to be back with the same guys and having a chance to write the future and look forward. I'm not gonna lie and say it doesn't sting, but we can't just dwell on it."
Bruins general manager Don Sweeney - speaking at the 2019 Prospects Challenge in Buffalo - said defensemen Kevan Miller (knee surgery) and John Moore (shoulder surgery) will not be ready for the start of camp. Moore said on Monday that his surgery, which occurred on June 26, requires a four- to six-month recovery.
"There's certain guys that we're gonna be careful with but they'll be participating," Sweeney said, while also mentioning Joakim Nordstrom (foot) and Zdeno Chara (elbow, jaw). "It's a long year. We knew that going in, that we were gonna be careful with some of the guys with more mileage."
