Anthony Davis scored 27 points to fuel the Los Angeles Lakers, who ended their two-game NBA losing streak in dramatic style Saturday with a 96-95 victory over the Celtics in Boston.

A well-rested Davis, who sat out the Lakers' loss to the Pistons in Detroit on Thursday with a bruised thigh, added 14 rebounds for the reigning NBA champions.

LeBron James finished with 21 points, seven rebounds and seven assists for the reigning NBA champions, who bounced back after defeats in Philadelphia and Detroit.

Jayson Tatum scored 30 points and pulled down nine rebounds for the Celtics and Jaylen Brown added 28 points.

It was a one-point game when Boston's Marcus Smart departed with 10:28 remaining after a fall that left him with what the Celtics said was a calf strain.

James drained a three-pointer to put the Lakers up 88-85 with 5:25 remaining and the Lakers pushed the lead to as many as seven points before the Celtics again narrowed the gap.

Tatum cut the deficit to 96-95 with 32.8 seconds remaining. Boston's Kemba Walker blocked a Davis shot but missed at the other end. Teammate Daniel Theis grabbed the rebound but couldn't get his follow-up effort to fall.

It came down to the buzzer in Chicago, where Portland's Damian Lillard drained a three-pointer as time expired to give the Trail Blazers a 123-122 victory over the Bulls.

Lillard finished with 44 points on eight three-pointers.

Chicago appeared headed for victory when Coby White made a pair of free throws to put the Bulls up 122-117 with 11.5 seconds remaining. But Lillard, whose 44 points included eight three-pointers, closed the ­deficit to 122-120 with a strike from beyond the arc with 8.2 seconds left.

The Blazers then forced a jump ball with 6.2 seconds left and Lillard was able to snag a loose ball and make the winner.

It was a narrow escape for a Blazers team that led by 19 in the third quarter.

Forward Lauri Markkanen scored 31 points and guard Zach LaVine added 26 for the Bulls.

And it was close in Miami, where Jimmy Butler returned from a 10-game absence due to the league's coronavirus protocols to score 30 points in the Heat's 105-104 victory over the Sacramento Kings.

"You simply cannot put a modern-day analytic to Jimmy's will to win," said Heat coach Erik Spoelstra, who still had to make do without injured Goran Dragic, Avery Bradley and ­others.
