Boston Celtics star guard Jaylen Brown will miss his second straight game against the Atlanta Hawks on Monday due to a nagging hip flexor problem.

The Celtics announced the news on Sunday. They shared it via Twitter/X.

The Celtics also listed forward Sam Hauser on the injury report as probable with treatment for lower back injuries and forward Kristaps Porziņģis as out due to left posterior tibialis tendon rehabilitation.

Porziņģis will be out for at least the next month.

Brown is dealing with a nagging hip flexor issue and will undergo a second MRI for the injury. He played in their first game against the Charlotte Hornets on Friday night, but missed the second game on Saturday night.

The 28-year-old is one of the Celtics’ best players, which is why they were crowned champions last season. Brown is off to a strong start in the 2024-2025 season, averaging 25.7 points, 7.2 rebounds, 3.8 assists and 1.5 steals per game. He has started the year well, so this hip injury could be a disappointment for Boston.

It’s unclear when this injury occurred, but he started to lack explosiveness in a recent game against the Indiana Pacers.

Celtics coach Joe Mazzulla called him “day-to-day” going forward.

Mazzulla also said it’s an injury that has bothered Brown lately and something “he’s played through.”

The Celtics are the deepest team in the league, so missing Brown for a handful of regular season games won’t hurt them in the long run. If Brown is indeed out for an extended period of time, it could hurt Boston if things start to get a little tight in the Eastern Conference standings.

Brown has spent his entire career in the Northeast, as the Celtics drafted him with the third overall pick in the 2016 NBA Draft.

In his nine-year career, Brown was an NBA champion, NBA Finals MVP, three-time NBA All-Star, All-NBA Second Team and NBA All-Rookie Second Team.

The Georgia native has improved every year of his career, and his jump from his rookie season to now is why Boston is the juggernaut that they are.

Brown has played in 546 games and averaged 18.7 points per game, 5.3 rebounds and 2.4 assists while shooting 48 percent from the field and 36 percent from three for his career.
