The English FA has received a letter from Chelsea about their controversial game at Reading when Petr Cech fractured his skull.

The Premiership champions were unhappy with Stephen Hunt's challenge on Cech and concerned with the medical procedure in place to help their stricken keeper.

Jose Mourinho, speaking last week, highlighted the time it took to get an ambulance to Cech but the club insist they are not trying to apportion blame.

Chelsea officials, however, are convinced important lessons can be learnt from the experience, which will offer quicker treatment in future for players who suffer serious injuries on the pitch.

The London club have put their observations in writing and the FA has promised to look into the points raised.

An FA spokesman said: "We have received a letter and will respond in due course to address their concerns."

Chelsea's letter includes their comments about Hunt's challenge on Cech but this is unlikely to persuade the FA's disciplinary chiefs to act against the Reading winger.

The FA announced last week that there would be no formal action taken against Hunt because referee Mike Riley dealt with the incident at the time.

This will not change but there will be discussions between the FA and the Premier League about the medical regulations in place at top-flight football matches.

Reading will be also asked to offer their thoughts on the issue.

A Premier League spokesman said: "We have received a letter as well in relation to the procedures. We will be asking Reading for their observations and the issue will be discussed in due course by the board."
