Ben Simmons has shaken off illness to help the Philadelphia 76ers to a franchise-record 15th straight win, putting them on the verge of third seeding in the NBA's Eastern Conference playoffs.

The young Australian was in doubt before the game due to stomach flu but he scored 14 points, grabbed 10 rebounds and claimed six assists plus six turnovers in a 121-113 away win over the Atlanta Hawks.

JJ Redick led the scoring for Philadephia with 28 points and Marco Belinelli added 20 points.

The 76ers can seal the No. 3 seed ahead of Le Bron James' Cleveland Cavaliers with a home win over the Milwaukee Bucks on Wednesday (Thursday AEST) in their final regular season match.

The Sixers lead the Cavaliers by one game heading into the final day of the regular season, with the Cavaliers to host the New York Knicks in their last game.

The match against the Bucks could be a first-round playoff preview. Milwaukee holds a 2-1 edge in the season series, with each team winning on its home court so far.

The 76ers haven't lost since a 101-98 home defeat by the Indiana Pacers on March 13 and they're headed back to the playoffs for the time since 2012.

They have maintained their latest winning streak without All-Star centre Joel Embiid for the past fortnight as he recovers from an eye socket fracture and he is expected back at sometime in the post-season.

Starting forward Dario Saric sustained an unintentional elbow to the mouth while battling for a rebound on the first possession of Tuesday's game. He suffered a lacerated upper lip and did not return.

Simmons picked up a technical in the third quarter for arguing all the way down the court about a call that didn't go his way.
