The Football Association is to investigate allegations of racism towards Tottenham defender Renee Hector by a Sheffield United player.
Hector has alleged an unnamed United player made "monkey noises" at her during Tottenham's FA Women's Championship away game on Sunday.
A statement read: "The FA can confirm that we are aware of an allegation of discriminatory abuse during The FA Women's Championship match between Sheffield United Women and Tottenham Hotspur Ladies on Sunday 6 January.
"We take all allegations of discrimination very seriously and will be making enquiries into the matter."
Tottenham confirmed they had reported the incident to the FA, while United said they had launched their own enquiry into the alleged abuse.
She said: "Such a shame that racism seems to be rising up again in football - I received some monkey noises (on Sunday) from an opposition player. The only reaction was to let the football do the talking and that we did great start to the year! ThlfcOfficial £COYSL £SHEvTOT £KickItOut".
The incident was reported by Hector to the referee during the game, Tottenham said.
