The 39-21 Philadelphia 76ers are 1.5 games behind the first-place Brooklyn Nets and two games ahead of the third-place Milwaukee Bucks heading into their matchup with the 20-40 Oklahoma City Thunder.

Here’s what to watch:

Simmons upgraded to questionable

Ben Simmons (illness) has been upgraded to questionable after being listed as out Sunday night. NBC Sports Philadelphia’s John Clark first reported the news. 

Joel Embiid (right shoulder soreness), Tobias Harris (right knee recovery), Furkan Korkmaz (right ankle sprain), and Paul Reed (health and safety protocols) are all questionable. Danny Green (left hip recovery) was also added to Monday’s 1:30 injury report as questionable. 

For the Thunder, Shai Gilgeous-Alexander (right foot plantar fasciitis), Luguentz Dort (right hip strain), and Mike Muscala (right ankle sprain) are notable players out. Dort scored a career-high 42 points earlier this month. Former Sixer Tony Bradley is questionable with a left ankle sprain.

2 losing streaks

The Sixers’ losing streak is at a season-high four games. The Thunders’, however, is at 13. The team hasn’t won a game in April. 

One of the Thunder’s defeats was against the Sixers, a 117-93 decision on April 10 in Oklahoma City. Embiid starred with 27 points and four blocks, while Korkmaz had 20 points and a career-high five steals. 

Chances for Maxey to shine

The Sixers’ recent problems with health have led to increased playing time for Tyrese Maxey. He’s averaged 20.9 minutes over the last five games, posting 11.8 points and 2.2 assists per contest. 

A developing player at 20 years old, Maxey has shown progress lately in mixing up his pace, settling for fewer floaters and executing at a higher level overall defensively.
