The 41-year-old received several fractured ribs and a collapsed lung after colliding with a goalkeeper while playing football last weekend and has spent the past week on sick leave.
While he was in considerable pain yesterday, he said his pride was in a much worse state.
''I was playing sport like a young man when I am clearly not,'' he conceded.
He spent a night under observation at Dunedin Hospital.
Mr Reddiex had recently returned to King's after spending 10 weeks on a Woolf Fisher Fellowship
in the United Kingdom, Europe and the United States, examining different teaching practices.
He said the beauty of the technological age was he had been able to continue some school work while lying horizontal in his armchair trying to alleviate the pain from his recent injuries.
Mr Reddiex planned to be back on deck at school fulltime today.
And although he was feeling his age, he had not been deterred from playing football and hoped to be back on the sports field by the end of the year.
