The Mount Sion clubman has had his injuries in recent years and was forced to sit out most of the 2009 campaign with a knee complaint.
However, Fitzgerald met with the veteran centre-back last week and was impressed by his determination to overcome his setbacks
‘Don’t have any doubt in your mind, Ken McGrath is mad to play for Waterford and you could tell that by him last week,’ said the Déise boss.
‘He is worried about the knees, naturally enough, but you have to stay positive. There is no point worrying until we know exactly what the story is and we will know that come March.’
