Josh Green's hot form has continued in the absence of Luka Doncic and Kyrie Irving for Dallas in their push for an NBA playoffs spot.

The Australian guard played 45 minutes as the Mavericks beat Texas rivals San Antonio 137-128 after overtime on Wednesday night.

The 22-year-old Green had 21 points, three rebounds, seven assists and a steal as the Mavs (35-35) improved to seventh in the Western Conference standings after outscoring the Spurs 16-7 in OT.

It's the third straight game in which he has scored 20-plus points, finishing on the night behind teammates Christian Wood (28 points), Jaden Hardy and Dwight Powell (both 22).

In Cleveland, Joel Embiid had 36 points and 18 rebounds and played the final 4:12 after initially being called for his sixth foul, leading Philadelphia to their sixth straight victory, 118-109 over the Cavaliers.

James Harden added 28 points and Tyrese Maxey had 23 for the Sixers, who were up 108-101 when Embiid was whistled for an offensive charge on Evan Mobley while making a jumper.

As Cavs fans began to celebrate Embiid's apparent exit, 76ers coach Doc Rivers immediately challenged the call, which was overturned after a replay review and the superstar was allowed to stay on the floor.

Philadelphia (46-22) remain third in the Eastern Conference, still one game behind Boston after the Celtics held on for a 104-102 victory at Minnesota.

The Grizzlies played their sixth game of eight without suspended star guard Ja Morant.

In Chicago, De'Aaron Fox hit a three-pointer with 0.7 seconds left to give Sacramento a 117-114 victory over the Bulls.

Fox scored 32 points on 12-for-17 shooting, hitting four triples for the Kings (41-27) to jump Memphis into second in the West.

Domantas Sabonis had his second straight triple-double - his 11th of the season - finishing with 14 points, 17 rebounds and 10 assists.

An undermanned Los Angeles Lakers, without LeBron James and Anthony Davis, were stunned in Houston 114-110.
