The Philadelphia 76ers' crashed out of the NBA playoffs amid a chorus of boos after the top seeds were sensationally upstaged by the Atlanta Hawks in Game 7 of the Eastern Conference semi-finals.

Back on home court for the series decider, the 76ers were tipped to close out the matchup at Wells Fargo Center on Sunday, but the fifth-seeded Hawks had other ideas following a stunning 103-96 victory.

Despite Trae Young's off night (21 points on just five-for-23 shooting), the Hawks still managed to conquer Joel Embiid and the 76ers thanks to unheralded guard Kevin Huerter.

Huerter had a team-high 27 points, seven rebounds and three assists as the Hawks returned to the Conference Finals for the first time since 2015, setting up a showdown with the Milwaukee Bucks.

It was a topsy-turvy battle in Philadelphia, where the 76ers trailed 76-71 at the start of the fourth quarter before rallying to lead by as many as four points in the final period.

This is the first time since 1994 that both No. 1 seeds in the NBA playoffs failed to make the conference finals.

However, the Hawks refused to surrender and pounced on the sloppy 76ers, who finished with 17 turnovers en route to bowing out of the postseason.

Double-doubles from MVP runner-up Embiid (31 points and 11 rebounds) and Tobias Harris (24 points and 14 rebounds) were not enough for the 76ers, with Ben Simmons (five points, 13 assists and eight rebounds) the subject of boos in his home arena after attempting just four shots throughout.

With Atlanta's victory, it is the first time since 1994 both number one seeds in the playoffs failed to make the Conference Finals after the Utah Jazz were ousted by the Los Angeles Clippers, according to Stats Perform.

Earlier in the day, the Phoenix Suns were 120-114 winners over the Clippers in Game 1 of the Western Conference Finals.

Devin Booker recorded his first career triple-double, posting 40 points, 13 rebounds and 11 assists for the second-seeded Suns in the absence of Chris Paul (COVID-19 health and safety protocols).

Booker – in the midst of his maiden NBA playoffs campaign – became the first Suns player to register a triple-double in the postseason since Hall of Famer Steve Nash in 2005.

The 24-year-old also became the third youngest player in NBA history to record a 40-point triple-double in the playoffs – only Luka Doncic and Hall of Famer Oscar Robertson have achieved the feat at a younger age.

The Clippers – featuring in the Conference Finals for the first time in their history – were without star Kawhi Leonard for a third consecutive game due to a knee injury.

Paul George (34 points) and Reggie Jackson (24 points) tried to inspire the fourth seeds on the road in the series opener.
