Iverson, the NBA’s leading scorer at 28.8 points a game, missed the 76ers’ 107-97 overtime loss at New Jersey on Monday due to flu-like symptoms.
Philadelphia is 1-5 this season without Iverson, who will make his sixth All-Star appearance this season. His status for this game is uncertain.
Though the Sixers lost for just the second time in six games, they missed a chance to reach .500 for the first time since a 6-6 mark Nov. 26.
Iverson, in his ninth season, has averaged 25.6 ppg in 15 career games against the Grizzlies. He had 25 points and seven steals at Memphis on Dec. 3, but the Sixers lost 94-86 in Mike Fratello’s debut as Grizzlies coach.
The Sixers are in danger of being swept by the Grizzlies for the second straight season, and third time in the last four. Philadelphia was 10-1 against the Grizzlies from 1995-2001, while the franchise was located in Vancouver, British Columbia, but has won just twice in the last six meetings.
The Sixers lead the all-time series 12-6, including 6-2 at home.
Willie Green, Iverson’s replacement in the lineup, had 28 points and six assist against the Nets. The second-year guard averages 11.2 points as a starter, and 6.1 as a reserve.
The Grizzlies have won 10 of 13, including a 108-96 home win over Minnesota on Tuesday that improved their mark to 22-10 since Fratello replaced the retired Hubie Brown on Nov. 27.
Six Memphis players scored in double figures against the Timberwolves, as the team shot 50 percent (41-for-82). Lorenzen Wright had 18 points and 12 rebounds, his fourth consecutive double-double. Stromile Swift also had 18 points for the Grizzlies.
Memphis got Bonzi Wells and Earl Watson back from injuries on Tuesday. Wells, the Grizzlies’ fourth-leading scorer at 11.2 points a game, had missed the last two games with a left leg sprain. Watson also returned from a two-game absence after sitting out with a right shoulder sprain.
