İdman.Biz reports that Liam Delap and Jami Gittens missed the team's last game due to a cold.
"Our doctors are doing everything they can to prevent what appears to be a virus, as some members of the headquarters have also fallen ill.
Today we had a meeting with the players about the need to wash our hands, the basic things that are really important, and I hope we can keep the infection under control.
We are going through a busy period and we need everyone to be fit and healthy," said the head coach of "the Blues".
