​The Bruins played the 2025-26 season without a captain. That won’t be the case for 2026-27.“We are going to announce a captain this year,” general manager Don Sweeney said Wednesday. Sweeney added the announcement will come before Boston’s Sept. 29 home opener against the Rangers. “We understand the legacy of our organization and we want to do it the right way,” Sweeney said. David Pastrnak, Charlie McAvoy and Hampus Lindholm were the three alternates last season. Sweeney said prior to Game 1 between the Sabres and the Bruins that he believed the next captain would emerge organically.“We took our time. We allowed the leadership group (to grow) last year, and we know who is at the forefront of that leadership group,” Sweeney said. “We’ve been talking about this for a while. We know exactly what we are going to do. But last year was a good example of allowing players who are going to be required in that leadership role to organically step forward. We are in a good place.”Pastrnak and McAvoy are the longest-tenured Bruins on the roster. Both players have been leaders in the locker room, with Pastrnak becoming more vocal over the season.OTHER TAKEAWAYS FROM DAY 1 OF TRAINING CAMPIs a Pavel Zacha extension coming?Fraser Minten signed a seven-year extension last week, which raised questions about what that means for Zacha, who’s in the final year of his contract. Sweeney said he has yet to “find a landing spot” with Zacha and his representatives, but that communication is ongoing.“We know the importance of Pav to our hockey club. We would like to have him be able to come back, so we’ll continue to talk between now and if we do find a deal,” Sweeney said. “But Pav’s a big part of what we’re trying to accomplish as an organization. Every player has its’ timeline for a deal and hopefully we get to a landing spot.”Zacha is coming off a strong 2025-26 season in which he set career-highs in goals (30) and points (65). He’s also arguably the Bruins’ best center and can play both up the middle and on the wing. Where does Matt Poitras fit on this team?The Bruins signed Poitras to a one-year, two-way contract on Wednesday just before training camp began. Since breaking camp as a 19-year-old in 2023-24, the center has struggled to carve out a full-time role with the club. Poitras underwent shoulder surgery in his rookie season, but has spent the majority of the last two seasons in Providence. Marco Sturm admitted that while he did a good job in last year’s camp, he still wasn’t ready to play at the NHL level.“He needed time in the minors, and those guys down there, they did a good job working with him,” Sturm said. “And when he got the call, he played some excellent games.”Sturm added that he sees Poitras as a center rather than a wing and expects him to play up the middle when practice begins Thursday. If the Bruins want to send Poitras to Providence, he will need to clear waivers. Will James Hagens mak
