The NBA players union is researching the Philadelphia 76ers for any possible breach of the collective bargaining agreement, sources told RealGM.

The NBPA told agents in a meeting on Monday that it will actively look into the 76ers’ handling of the CBA, such as salary distributions, the cap floor and contract format loopholes. For the NBPA, Philadelphia’s approach over the past several seasons may not be a technical violation of collective bargaining as much as it is one of the spirit of negotiating under the CBA.

An NBPA spokesperson confirmed Tuesday the union’s plan to pursue the 76ers’ issue if there is a violation found.

Over the past two seasons, the 76ers have compiled a 37-127 record, staying below the 90 percent salary floor for majority of the campaigns before late season signings or trades.
