The Philadelphia 76ers announced on Monday that they have made the decision to fire coach Brett Brown.

Brown, who has coached the 76ers for seven seasons, is expected to be the antecedent for more upset for the team as they begin exploring changes in the front-office structure, per Fox Sports.

General manager Elton Brand will continue to oversee basketball operations but the franchise's personnel and structure will go under evaluation as change looms.

Sources say that senior leadership are keen to keep the Sixers' two young All-Stars, Joel Embiid and Ben Simmons together, as they let new coaching staff maximise their playing capacity together before trade discussions commence.

Brand met with Brown on Sunday in Orlando, where players were asked to conduct exit interviews with Brown before he travelled back to Philadelphia on Monday.

Under Browns contract, he is still owed several million dollars by the 76ers from now until the end of the agreement.

"I have a tremendous level of respect for Brett both personally and professionally and appreciate all he's done for the 76ers organization and the City of Philadelphia," Brand said in a statement.

"He did many positive things during his time here, developing young talent and helping position our team for three straight postseason appearances.

"Unfortunately, we fell well short of our goals this year and I believe it is best to go in a new direction.

"This will be an important offseason for us as we look to get back on track towards our goal of competing for an NBA championship."

The Sixers' plan on looking at LA Clippers assistant coach Tyronn Lue to replace Brown, as he has ability to connect and command the respect of high-level players.

Another target on the Sixers' hit list is Villanova's two-time national championship coach, Jay Wright.

Although the search is expected to expand, these two candidates are who the Sixers' need as they have championship and high-level player experience.

Brown is still a well-respected individual within the franchise, but after seven season the organisation believed they had gone as far as they could with Brown.

"In 2013, I was employed to lead one of the most dramatic rebuilds in professional sports history," Brown said in a statement.

"In the past seven years, our players and coaches have evolved and grown, and I have deep appreciation for the 102 players I have coached."
