FIFA handed the Blues their transfer ban in February after an investigation found them to have breached rules regarding the signing of foreign players under the age of 18 on 29 counts.
After their appeal was rejected by the aptly named FIFA Appeal Committee, it was understood they would then turn to CAS as a final resort. However, according to reports from Sky Sports, with three weeks passing since that judgement, the club have still not submitted the case for re-examination with the body.
The Blues' statement upon the previous rejection proclaimed: "Chelsea FC has today received the decision of the FIFA Appeal Committee. The club is very disappointed that the transfer ban of two consecutive registration periods was not overturned.
"Chelsea FC categorically refutes the findings of the FIFA Appeal Committee. It acted in accordance with the relevant regulations and will appeal the decision to the Court of Arbitration for Sport (CAS)."
