Crystal Palace have branded allegations that one of their players racially abused Cardiff's Michael Chopra as 'outrageous'.
Cardiff striker Jay Bothroyd claimed after Saturday's 1-1 draw in Wales that his team-mate Chopra had been the subject of a slur from a Palace player.
Players from both sides had to be separated following the final whistle, and trouble reportedly continued down the tunnel.
It is understood that referee Steve Tanner did not hear the alleged remark but the Football Association will look into the matter after reading his report.
Palace are happy to co-operate with any inquiry but do not believe any of their players would behave in such an unacceptable manner.
"Crystal Palace FC would welcome any FA inquiry into racist comments allegedly made by one of our players at Saturday's match at Cardiff City," read a club statement.
"Crystal Palace is a multi-ethnic club and is proud of its history in this respect. We take great exception at the outrageous allegations being levied at us by Cardiff City players and management.
"We would like to make it known we are 100% supportive in this matter of all of our players and definitive in our belief none of them would make any racist comments.
"As a club we are fully behind the Kick Racism Out of Football campaign, as are all of our players."
