The amount of relief is based on whether Samhna has another club in the MLS programs and the salary they agree.
McCann, a $ 318,000 last season, had a salary guaranteed last season, according to the MLS Participants Association. He made 45 appeals, including 31 the previous two starts.
If McCann is a sign of salary less than he did last season, Atlanta United must pay the difference.
If McCann covers exceptions, his budget charge will count against Atlanta United.
However, a single-player club with a Guaranteed Contract is allowed to buy during the leave and free space corresponding to the budget. Atlanta United has yet to buy its exercise.
