Career
Sidebottom was already 24 when he began his VFL career in 1983, having played for Swan Districts in Western Australia since 1977 and played in their 1982 premiership team A ruckman, Sidebottom played only nine games in his first season for Street Kilda but was a regular fixture in the side the following year after the retirement of Jeff Sarau. After making another 17 appearances in 1985, Sidebottom played just eight more games over the next one and a half seasons and midway through crossed to Fitzroy.
Only able to play one senior game for Fitzroy, Sidebottom returned to Swan Districts in 1988 for one final season and retired owing to ankle and back injuries with 98 WAFL games to his name.
He had also played a State of Origin match for Western Australia against Victoria back in 1985, sharing the ruck duties with Andrew Purser.
