The FA is reportedly investigating a yellow card received by an Arsenal player in a Premier League game this season amid concerns over suspicious betting patterns.
Sixteen different Arsenal players have been cautioned in the 2021-22 top-flight campaign, but the identity of the member of Mikel Arteta's squad involved has not been disclosed.
A report from The Athletic claims that the FA are looking into a yellow card after bookmakers pointed out an "unusual amount of money" being placed on the caution in that game.
"The FA is aware of the matter in question and is looking into it," the FA told The Athletic, who claim to know the player's identity but will not be revealing it due to privacy reasons.
Gabriel Magalhaes, Rob Holding, Thomas Partey and Martin Odegaard have two yellow cards to their names, while Cedric Soares, Pablo Mari, Gabriel Martinelli, Aaron Ramsdale, Ben White, Nuno Tavares, Takehiro Tomiyasu and the recently-departed Sead Kolasinac have been booked once in this top-flight campaign.
