D.C. United terminates Fountas' contract amid racism allegations, despite polygraph test result

D.C. United is terminating forward Taxi Fountas' contract due to accusations of racial abuse.
Fountas was previously accused of racial abuse and is under MLS investigation.
Fountas took a polygraph test in his defense, which reportedly showed no deception.
Terminating Fountas' contract will free up roster and cap space for D.C. United.
The accuracy of polygraph tests is debated, and results are often inadmissible as evidence.
