Union to file grievance against Kings

The National Basketball Players Association is filing a grievance against the Kings on behalf of forward Luc Mbah a Moute, who had a contract he signed with the team last month voided after a failed physical, according to a Yahoo Sports report.

The Kings reportedly were concerned about Mbah a Moute’s right shoulder, but the free agent and Cameroon native was cleared to play for Team Africa against Team World in the first NBA exhibition game in Africa on Saturday.

Mbah a Moute signed a one-year deal July 14. He averaged a career-high 9.9 points in 67 games for Philadelphia last season.
