Former Australian captain and respected commentator Ian Chappell on Thursday revealed he is battling skin cancer but the 75-year-old expects to be fit enough to commentate when the Ashes comes calling next month. Chappell, who played 75 Tests for Australia between 1964 and 1980, has completed five weeks of intense radiation therapy after he had skin cancers removed from his shoulder, neck and underarm. “When you hit 70 you feel (vulnerable) anyhow, but I guess I’ve got so used to bloody skin cancers over the years, and the fact that none of them have been melanomas, probably provides a bit of comfort. It may be naivety on my part,” Chappell told The Daily Telegraph.
