The Sixers (4-15) continue their homestand against the Boston Celtics (11-8) at the Wells Fargo Center on Saturday night (7:30 p.m./CSN and CSNPhilly.com).

Let's take a closer look at the matchup.

1. A green giant-sized challenge
Just crumple it up and move on.

That's about the only thing the Sixers can do after getting ran out of the gym by the Orlando Magic on Friday. Instead of looking like a team that hadn't played since Monday, the Sixers appeared flat in a 105-88 loss.

Outside of Joel Embiid's first 20-point, 10-rebound game (he had 25 points and 10 boards) and a strong effort from Jahlil Okafor (16 points and 13 rebounds), not much else went right for the Sixers.

Now Embiid will sit the second game of a back-to-back set and Okafor will be thrust into the starting lineup, as the Sixers try to deal with Boston big man Al Horford. 

Horford, the Celtics' prized free-agent acquisition, is coming off his best game so far for his new team. He recorded 26 points, eight rebounds and six blocks in the Celtics' 97-92 win over the Kings on Friday.

2. Little big man
Even with Horford coming off a productive performance, the Sixers' game plan against the Celtics has to focus on slowing down Isaiah Thomas.

The 5-foot-9 guard continues to put up big numbers in the scoring department. Despite his shooting percentages taking a dip this season, Thomas still ranks ninth in the NBA with a career-high 25.7 points per game. 

 

And even though he is a willing passer (averaging a career-high-tying 6.3 assists), expect Thomas to try and score early and often against the Sixers. After all, the reserve-turned-All-Star has put up 21.5 points per game against the Sixers during his career, his highest mark against any opponent.

3. Dial up the long-distance defense
The Sixers need to be aware of Thomas and just about all of his teammates when they toe that three-point line.

The Celtics rank fifth in the league in three-pointers attempted (31.1), three-pointers made (11.3) and eighth in three-point percentage (36.3) per game.

The C's have four players shooting above 40 percent from beyond the arc, and perhaps a bit surprising, three of them are big men. Jonas Jerebko (46.4 percent), Horford (42.4 percent) and Amir Johnson (40.0 percent) have all been on target from long range.

4. Injuries
Robert Covington (knee) and Jerryd Bayless (wrist) are both questionable. Embiid (rest), Nerlens Noel (knee) and Ben Simmons (foot) are out for the Sixers.

The Celtics have no players listed on the injury report.

5. This and that
• The Sixers have lost five games in a row overall and eight straight to the Celtics.

• The Celtics rank 25th in rebounding with 42.2 a night.

• Dario Saric had two points Friday against the Magic and has failed to reach double digits in scoring five of his last six games.
