Ashley Cole has been interviewed as part of the Football Association's investigation into allegations by Chelsea that referee Mark Clattenburg used inappropriate language towards their midfielder John Obi Mikel.
Sources close to the investigation have confirmed that England defender Cole was one of the Chelsea players interviewed by the FA.
Clattenburg will miss a fourth weekend of matches as Chelsea's complaint against him continues to hang over the referee.
The FA's investigation into Chelsea's allegation that Clattenburg used inappropriate language, understood to have been interpreted as racist, towards Mikel is still continuing and a decision is expected later this week.
Clattenburg does not want to take charge of any matches while the case is ongoing and so was not considered for any of this weekend's games.
The FA have interviewed several Chelsea players, including Mikel, as well as Clattenburg, assistant referees Michael McDonough and Simon Long and fourth official Michael Jones.
An independent QC is studying all the evidence in close detail before recommending a decision.
