MLS said it will investigate the alleged use of a racial slur in Sunday's match between Inter Miami and D.C. United, in which it is alleged that DCU forward Taxi Fountas directed the N-word at Inter Miami defender Damian Lowe.

"MLS has zero tolerance for abusive and offensive language and we take these allegations very seriously," an MLS spokesperson said in a statement to ESPN. "An investigation into this matter will begin promptly. Further information will be provided upon completion of that investigation."

A D.C. United spokesperson also issued a statement, which read: "D.C. United are aware of the allegations involving a player during the match against Inter Miami CF. The club will work closely with Major League Soccer and Inter Miami to investigate the incident."

Fountas issued his own statement on his social media on Monday, denying the allegations and saying that he was upset to be falsely accused.
