Jaylen Brown is counting his lucky stars as the Boston Celtics man feels blessed with another chance at achieving "something special".

Brown posted 27 points, one more than teammate Jayson Tatum, as the Celtics overcame the Portland Trail Blazers 121-99, despite the absence of injured stars Jrue Holiday and Kristaps Porzingis.

That victory over Portland marked the Eastern Conference-leading Boston's 50th of the season for a third straight campaign.

"All the guys laugh because, around this time of year, I say the same thing – how much of an honor it is to be on this team," Brown said.

"I'm grateful to be on a team that's winning, that's been playing the right way, has another opportunity to do something special. That's a blessing."

With a mammoth 18 games remaining, the Celtics have already secured a playoff spot after becoming the first team to hit the 50-win mark this year.

Boston lost the NBA Finals to the Golden State Warriors in 2022 before Conference Finals defeat against the Miami Heat the following year, though Tatum remains buoyant.

"At this point of the season, to have 50 wins, it means we're doing something right," Tatum added. "The scary part is, we can get better."

Sam Hauser also finished with a season-high six 3-pointers and 22 points for Boston, who have won an NBA-leading 21 games on the road this season.

"We don't really look at a team's record," Hauser said. "It's the NBA, everybody has talented players.

"You can lose any given night, so we just try to take it one day at a time, once game at a time, and find things that we can get better at each and every day."

The Celtics will hope to keep up their winning run on the road when they visit the Utah Jazz on Tuesday.
