Robinson spent the 2002-03 season with the Hawks, averaging a team-high 20.8 points before being traded to Philadelpia in a four-team deal on July 23.
The two-time All-Star missed the Nov. 29 matchup with Atlanta because of a sprained left ankle. The 76ers won that game 98-86 at the Wachovia Center.
Allen Iverson scored a season-high 50 points to lead Philadelphia in that victory, but he will not play Tuesday. He sat out Monday’s 76-66 home loss to Detroit with a sore right shoulder, an injury he suffered in a 112-101 victory at Seattle on Thursday.
Iverson, tied with Orlando’s Tracy McGrady with an NBA-best 27.4 points per game, has averaged 29 points in 26 career games against the Hawks.
Without Iverson on Monday, Philadelphia shot 30.1 percent (25-for-83) and tied its second-lowest point total since 1954-55.
Aaron McKie, who replaced Iverson in the lineup, added two points.
“Without AI, our guys gave us a legitimate shot to win,” Sixers interim coach Chris Ford said.
The Sixers, 1 1/2 games out of the final playoff spot in the East, are 2-3 under Ford.
The Hawks are coming off a 123-121 triple-overtime loss at Houston on Sunday night in the NBA’s longest game since 2000-01.
It was Atlanta’s third straight loss after winning three of four— its best stretch of the season.
“We had plenty of opportunities to win it, but we didn’t seize the moment,” said Terry, who is averaging 22.3 points over his last three games.
The Hawks, who haven’t made the playoffs since the 1998-99 season, are six games out of a spot.
