He was the first East Fremantle player to play 250 games and represented Western Australia on 7 occasions, including the state's second ever National Carnival winning team in 1961.[1][2] He played in the finals in every season that he played, including eight grand finals, but was only part of a successful premiership in 1957.[3] Known primarily as a tough defender, he could also play forward, leading the East Fremantle goalkicking in 1955 with 65 goals.[4]
After retiring from WANFL football he continued to play and coach in Katanning and Donnybrook, where he was stationed as a police officer.[5]
Many other members of his extended family also played football and other sports in Fremantle, including former AFL players Daniel Kerr and Shaun McManus, and the women's football player Sam Kerr.[8]
Following his death whilst on holiday in Canada with his wife Beryl, the Fremantle Football Club paid tribute to Regan by wearing black armbands and having a minute of silence before their Round 7 game against Hawthorn at Subiaco Oval on 12 May 2007.[5]
