Ben Simmons will miss the Philadelphia 76ers' NBA season opener against the New Orleans Pelicans after being handed a one-game suspension.

Simmons demanded a trade amid the fallout from last season's playoff exit to the Atlanta Hawks. He was absent for the first two weeks of preseason work before showing up on October 11 to begin fulfilling COVID-19 protocols that would allow him to re-join the championship-chasing franchise.

Coach Doc Rivers told reporters on Monday he had "no idea" whether Simmons would play in the opening game of the 2021-22 season on Wednesday night, adding: "When it comes, I'll make the decision. But I'm just going to wait and see and watch. The spirit has been so good, and so we're just going to keep going."

On Tuesday, the 76ers announced Simmons was suspended for the Pelicans game due to "conduct detrimental to the team". According to reports, the three-time All Star was ejected from practice after Rivers grew frustrated with his lack of engagement.

The Australian, who has four years and $147million left on his max contract, was criticised for his shooting performance during the 2021 postseason, in which the 76ers were eliminated in the semi-finals.

The former number one draft pick had no fourth-quarter field-goal attempts in his final four games of the playoffs against the Hawks. He is the only NBA player in the past 20 seasons to have four consecutive postseason games with no field-goal attempts in the fourth quarter during a season in which he was an All-Star, according to Stats Perform.

Simmons averaged just 10.1 field-goal attempts in 2020-21 – a career low, which dropped to 7.9 in the playoffs. It was the same story with his scoring as he posted a career-worst 14.3 points per game and 11.9 in the postseason.

Free throws became a theme of his problematic playoffs. Simmons made just 25 of 73 shots in the 2020-21 postseason. his 34.2 free-throw percentage the lowest ever such figure for players with a minimum of 70 attempts.
