Ben Simmons has filed a grievance against the Philadelphia 76ers in an attempt to recoup lost salary from fines this season. Simmons was fined nearly $20 million by the Sixers throughout his time with the team from October through the trade deadline in mid-February.

Philadelphia traded Simmons to the Brooklyn Nets at the trade deadline, but that came after the guard missed the entire season with the 76ers. Simmons initially refused to report to the Sixers in the early part of the season. He eventually did report, but was sent home after refusing to work up to Philadelphia's desired level.

Simmons and his camp have cited both a long-term back injury, which has held him since arriving to the Nets, and mental health issues were what kept him from fully joining the Sixers. Philadelphia says Simmons refused to take part in treatment plans and to work with the team to return to playing.

The grievance will now head to arbitration. The NBPA is supporting Simmons in his attempt to reclaim his lost salary.
