England's selectors experimented with young players in the first two matches of the 1929 series against South Africa, and Killick was picked to partner Herbert Sutcliffe as an opener.

Across the 1930s, as he first studied for the Anglican priesthood and then worked for the Church, he played infrequent first-class cricket, not appearing at all between 1934 and 1938.
He died from a heart attack while playing in an inter-diocesan cricket match between clergy from the St Albans and Coventry dioceses, aged 46.
