Veteran guard Jason Richardson will miss his fifth straight game on Wednesday night against the Washington Wizards, and from the sound of things, he likely will miss another game or two.

Richardson will be departing for Vail, Colo. on Wednesday night to meet with renowned knee surgeon Dr. Richard Steadman for an examination of his ailing left knee.

Steadman is well known in basketball circles for performing microfracture surgery. He also works closely with the U.S. ski team and was inducted into the U.S. Ski Hall of Fame.

Steadman also performed surgery on Kobe Bryant's knee in the summer of 2003 when he was arrested for his connection with a sexual assault complaint.

Richardson has not played since Jan. 18 and had his knee drained of 20 ccs of fluid last week. When Richardson has played, he has not performed well in his last 10 appearances, averaging 7.7 points per game over that span while shooting 10 for 42 (23.8 percent) from three-point range.

Richardson, 32, was acquired from Orlando as part of the trade that brought Andrew Bynum to Philadelphia and sent Andre Iguodala to Denver and Nik Vucevic and Maurice Harkless to Orlando.

In 33 games this season, Richardson averaged 10.5 points, 3.8 rebounds and was shooting 34.1 percent from three-point range -- his lowest percentage since his rookie season in 2001-02.

Wilkins not with the team

Shortly prior to Wednesday night's tip at the Wells Fargo Center, the Sixers announced that veteran guard/forward Damien Wilkins was not with the team.

According to a team spokesman, Wilkins was attending to personal matters.

In recent weeks, Wilkins has emerged as part of coach Doug Collins' rotation because of his defense and veteran savvy. With Wilkins not available, expect his minutes to fall to guard Dorell Wright.
