1. The Sixers struggled to find their offensive rhythm after Joel Embiid left the game following a hit to his face. Embiid's absence was evident as the team looked out of sync and unable to generate quality looks on offense. 2. The Pacers took advantage of Embiid's absence by attacking the paint and exploiting the Sixers' depleted frontcourt. They were able to score easy baskets inside and control the game in the paint, ultimately leading to their victory over Philadelphia. 3. Without Embiid anchoring the defense, the Sixers also struggled to contain the Pacers' offensive attack. Indiana was able to move the ball effectively and find open looks, shooting at a high percentage and keeping the Sixers on their heels throughout the game.

Joel Embiid played just one half and the Sixers failed to add an eighth win Friday night.

They dropped to 7-16 this season with a 121-107 loss to the Pacers.

Embiid did not play the second half after being unintentionally stuck on the right side of his face by Indiana's Bennedict Mathurin. He will undergo further testing, a Sixers official said.

The Sixers were without Caleb Martin (right shoulder impingement) and Adem Bona (left knee tendinopathy). Both players have resumed on-court work and are considered day-to-day. Kyle Lowry was scratched late because of lower back spasms.

Tyrese Maxey scored a team-high 22 points. Paul George added 15 and Kelly Oubre Jr. recorded a 12-point, 13-rebound double-double.

Tyrese Haliburton led the 11-15 Pacers with 32 points and 11 assists. Pascal Siakam had 23 points and eight boards.

Next up for the Sixers is a road game Monday night against the Hornets. Here are observations on their defeat to Indiana:

Embiid’s passing was a plus in the early going.

The superstar big man tallied four first-quarter assists. Oubre cut behind the Indiana defense on the game’s first play and Embiid dished to him for a layup. The Sixers had a few nice inside-out moments from multiple players’ post-ups, including an Embiid feed that set George up for a wide-open three-pointer.

The Pacers responded to a 9-2 deficit by storming back with a 14-0 run. The Sixers’ turnovers played a key part, allowing Indiana to attack in transition. Mathurin poked the ball away from an unsuspecting George, leading to Haliburton’s second consecutive three. He made four triples in the first period.

Maxey turned the ball early in the second quarter over when the Pacers blitzed him in the pick-and-roll shortly after he crossed half court. Seconds later, T.J. McConnell tossed a successful alley-oop to Obi Toppin and Indiana took a 37-24 lead. At that point, the Sixers had eight turnovers to the Pacers’ one.

Indiana applied effective pressure on Maxey, who’d scored 45 points on Oct. 27 in an overtime victory against the Pacers. Before Friday, his season high in turnovers was four. He had five giveaways in the first half.

It didn’t help that the Sixers came up empty on several decent looks. Embiid missed a driving layup on Myles Turner and began 0 for 4 from the floor. He’d started 0 for 7 in the Sixers’ win Sunday over the Bulls.

Eric Gordon was the lone available Sixer not in the team’s 10-man rotation.

While the team’s second unit had some defensive breakdowns, the youthful trio of Jared McCain, KJ Martin and Ricky Council IV combined for 16 first-half points.

Once he checked back in for his second stint, Embiid was determined to go at Turner inside. He drew Turner’s third foul with 4:49 left in the second quarter.

All attention turned to Embiid's health at the tail end of the second. He was hit in the face by Mathurin's arm as the Indiana guard pursued a potential offensive rebound. Embiid eventually rose to his feet and walked back to the Sixers' locker room holding a towel to his face. He did not come back to the floor.

It's unsurprising that the Sixers would want to thoroughly evaluate Embiid, who has twice worn a mask on his face during the playoffs after returning from orbital fractures.

McCain started the third quarter and had an injury scare of his own when he fell hard on a drive and appeared to hit his head against the court. According to a Sixers official, McCain was assessed for a concussion and cleared to return.

The Sixers fell behind by as many as 18 points in the third quarter.

They surged back into the game late in the third period, though. Oubre, Council and Drummond all played hard and did good, physical work on the boards.

Sixers head coach Nick Nurse used George and four bench players to begin the fourth quarter. George grew more aggressive, sinking a floater and a jumper that cut the Pacers' lead to 92-87.

In the end, the Sixers seemed to run out of juice and Indiana made enough timely shots, including two Siakam jumpers in a row. Haliburton scored an and-one hoop on McCain and then stopped by the bench to celebrate with his teammates. The Pacers' lead kept expanding and they cruised to victory.

For the Sixers, all the important questions yet again revolve around the health of Embiid.
