Kenneth Howard "Killer" Kearney was an Australian rugby footballer – a dual-code international player – and a rugby league coach. He represented the Wallabies in seven Tests, and the Kangaroos in thirty-one Test matches and World Cup games. He captained Australia in nine rugby league Test matches in 1956 and 1957. He was a hooker and captain-coach with the St. George Dragons in the first half of their eleven-year consecutive premiership winning run from 1956 to 1966. He is considered one of Australia's finest footballers of the 20th century.

Hooker is one of the positions in a rugby league football team. Usually wearing jersey or shirt number 9, the hooker is one of the team's forwards. During scrums the hooker plays in the front row, and the position's name comes from their role of 'hooking' or 'raking' the ball back with the foot. For this reason the hooker is sometimes referred to in Australia as the rake. Hookers have a great deal of contact with the ball, as they usually play the role of acting halfback or dummy half, picking the ball up from the play-the-ball that follows a tackle. Hookers therefore have much responsibility in that they then decide what to do with the ball, whether that be to pass it, run with it, or occasionally to kick it. Therefore, together with the two halves and fullback, hooker is one of the four key positions that make up what is sometimes called a team's 'spine'. A trend of halves converting into hookers followed the introduction of the 10 metre rule, and many players have switched between these positions in their careers such as Geoff Toovey, Andrew Johns, Craig Gower and Peter Wallace.
