Coventry City have issued the following statement regarding the blowing of whistle at home matches.
"The Club urges fans to stop blowing whistles inside the stadium on a Coventry City FC Matchday.
The Football Association (FA) has written to the club and made it abundantly clear that they will continue to monitor Coventry City fans' behaviour inside stadiums and any deliberate disruption of a game by our fanbase will leave the Club open to FA sanctions.
Whilst the Club will always encourage vocal support in favour of the team, we kindly ask that fans refrain from blowing whistles that may cause distraction and/or interrupt a match."
