James Harden scored 42 points as Philadelphia 76ers beat Boston Celtics in overtime to level their play-off series at 2-2.
Harden scored to send the game into overtime, then made the decisive three-pointer to clinch a 116-115 win.
Philadelphia 76ers led for much of the game before a late surge by Boston Celtics helped them move into the lead.
Phoenix Suns beat Denver Nuggets 129-124 to ensure their series is also level going into game five.
Devin Booker and Kevin Durant scored 36 points each, while Landry Shamet was a surprise hero coming off the bench to score 14 of his 19 points in the fourth quarter.
Booker shot 14-for-18 and registered 12 assists, while Durant added 11 rebounds and six assists as the fourth-seeded Phoenix Suns won their second straight game.
A career-best 53-point display by Nikola Jokic, came in vain for top-seeded, Denver Nuggets.
Jokic was given an unsportsmanlike technical foul just before half-time after an incident involving Mat Ishbia, who became Phoenix Suns’ owner in February.
The ball went out of bounds and ended up in the hands of Ishbia, sitting in the front row. As Jokic tried to get the ball back, Ishbia held on to it and after it came loose, the Jokic pushed Ishbia with the outside of his forearm, sending the 43-year-old back into his seat.
For the third-seeded Philadelphia 76ers, Embiid supported Harden with 34 points, while Jayson Tatum (24), Jaylen Brown (23) and Marcus Smart (21) helped to keep Boston Celtics in the game until the dying seconds.
Smart thought he had won it for the second seed in the Eastern Conference, Boston Celtics, but his last-ditch three-pointer came after the buzzer.
Game five in their best-of-seven series will be tomorrow in Boston, while Phoenix Suns and Boston Nuggets will meet again in Denver tomorrow.
