UNLIKE THE TEAMS in the NCAA Tournament, it could be none and done for Andrew Bynum as a 76er.

The Sixers announced at halftime of Monday night's game against the Portland Trail Blazers that the 7-foot, 300-pound Bynum will have surgery on Tuesday, thus ending one of the most frustrating situations in team history.

Bynum, who has not played all season, will undergo arthroscopic surgery on both knees. It will be performed by Dr. David Altchek, of the Hospital of Special Surgery in New York.

"After many months of rehabilitation and consulting with numerous doctors, Andrew and the doctors treating him determined that this is the best course of action at this point," said Sixers general manager Tony DiLeo. "We will continue to monitor and evaluate his status moving forward."

How the Sixers will move forward will be the biggest question surrounding the organization in quite some time. DiLeo said repeatedly during the season that Bynum was "Plan A." But Bynum, who is making $16.5 million this season on the final year of a contract he signed with the Lakers, can become an unrestricted free agent after the season. The Sixers will have to decide whether Bynum will be healthy enough to continue his career, if indeed he wishes to return to the team.

Bynum, 25, was obtained during a four-team trade in August that cost the Sixers Andre Iguodala, Nikola Vucevic, Maurice Harkless and a protected first-round draft pick. In mid-September, Bynum hurt his right knee while working out to get ready for training camp. It was announced the day before training camp that he would be out for about 3 weeks, but could be ready for Opening Night.

As that injury lingered, it then was learned that Bynum hurt the left knee while bowling in mid-November. While he said his right knee was feeling better, the left was slow to respond following the bowling incident. After upping his workouts to a more strenuous schedule, Bynum attempted to play five-on-five during a practice. The stint lasted just a few minutes, and a week later it was revealed that Bynum's right knee was again hurting.

And now comes word of the surgery.

Hopes were high for the Sixers after they obtained Bynum, who averaged career highs in points (18.7) and rebounds (11.8) last season with the Lakers, playing 60 of 66 games in a lockout-shortened season. Hopes have faded to disappointing reality as Bynum will not see the court this season.

Whether the team is willing to take another chance on him will no doubt be a heavy topic.
