"We are happy with what we do for the players," he said.
"Our players are scanned every two years and someone coming to the club on a transfer or a young boy at 17 is scanned immediately."
He pointed out that stricken Bolton midfielder Fabrice Muamba was also checked recently but the problem was not detected showing the difficulty of detecting such medical problems.
"I don't know how accurate the scanning is for everyone; Fabrice was also scanned - I'm led to believe four times - but you are not going to pick everything up and maybe he's been a little bit unfortunate.
"The encouraging thing is there has been positive news coming out, but he has a long way to go and he still needs the help and support and prayers of everyone in the footballing world to help him get over this.
He also had words of advice for the 23-year-old noting that life after the incident will be remarkably different from before.
"It is encouraging for him but we have to be cautiously optimistic because I think there are going to be ups and downs for the boy.
"But most importantly he is moving in the right direction and is progressing but I think it will be slow."
