LeBron James' 41 points were not enough to prevent his Los Angeles Lakers from going down 125-121 in a controversial overtime loss on the road against the Boston Celtics.

In the latest edition of the league's most decorated rivalry, James was a man on a mission, finishing 15-of-30 from the field, six-of-12 from deep and five-of-six from the free throw line as the only Lakers player to score more than 16.

He added nine rebounds and eight assists, and he should have been awarded potential game-winning free throws after he was clearly hit on the arm while driving for a layup with under a second remaining in regulation.

But the Celtics got the call in Boston, and it would be Jaylen Brown stepping up in the extra period to deliver a win for the home fans.

Brown scored 11 of his team-high 37 points in overtime, finishing 13-of-23 from the field with nine rebounds, picking up the slack for team-mate and MVP candidate Jayson Tatum.

Tatum had a respectable stat line of 30 points, 11 rebounds, four assists and two steals, but he shot a dismal eight-of-25 from the field, while Sixth Man of the Year contender Malcolm Brodgon chipped in a game-changing 25 points (eight-of-15), six rebounds, four assists and two steals off the bench.

For the Lakers, it was Anthony Davis' second game back after five-and-a-half weeks on the sideline dealing with a foot injury, and he came off the bench again for 16 points (six-of-15), 10 rebounds and four assists in 34 minutes.

The win snapped a three-game losing streak for the Celtics, and improved their league-leading record to 36-15. 

The Lakers fell to 23-27, and although they sit 13th in the Western Conference, they are only three games behind the Minnesota Timberwolves in the sixth seed.

Clippers extend winning streak to five

The Los Angeles Clippers are enjoying their longest winning streak of the season after making it five in a row with Saturday's 120-113 victory against the Atlanta Hawks.

The Clippers were led by their resurgent two-time NBA Finals MVP Kawhi Leonard, who scored a game-high 32 points on 12-of-20 shooting while adding eight rebounds and four assists.

There were fears Leonard's prime had been stolen from him by injuries after scoring a total of 50 points in his first five games of this campaign, but over his past 10 fixtures he sits eighth overall in points per game at 29.3.

Over that span he is shooting 55.6 per cent from the field, 47.2 per cent from deep and 92.5 per cent from the free throw line while adding 7.0 rebounds, 3.8 assists and 1.9 steals per game, improving the Clippers' record to 28-24.

Kyrie stays red-hot in New York showdown

Brooklyn Nets guard Kyrie Irving posted his sixth consecutive game with at least 30 points and six assists to defeat the New York Knicks 122-115 at home.

Irving, who was named an All-Star starter mid-week, scored a game-high 32 points on 12-of-27 shooting with nine assists, six rebounds and two steals.

Over his past six games, his 36.3 points per game is eclipsed only by Portland Trail Blazers icon Damian Lillard (38.3), while Irving's 7.8 assists would also be a new career-high as he shoulders a massive workload in the absence of injured superstar Kevin Durant.
