When Adam Treloar runs out for the Bulldogs against Fremantle after the bye, he will become a member of a very exclusive circle.

For Treloar, it will be his 50th game as a Dog, following his 79 games for GWS and 94 for Collingwood.

As a result, Treloar will become just the fourth player in V/AFL history to play 50 or more matches for three different clubs. And he has club links to the first two footballers to do so.

The first footballer to play 50 games for three clubs, like Treloar, had Whitten Oval as his third home.

That player was Glenn Coleman. Coleman's VFL career began as a Lion. He played 64 games from 1980 to 1985 before joining the Sydney Swans in 1986. Coleman's four years in Sydney yielded 61 games.

In 1990, the year the VFL became the AFL, Coleman changed clubs again, joining Footscray. In his first season as Bulldog, Coleman made an impact in more ways than one.

Coleman polled nine Brownlow Medal votes that year (teammate Tony Liberatore winning the award with 18), and capped off his excellent season in a most unusual way. In the final game of the season, the man mountain collided with one of the point posts at the Barkly Street end of Whitten Oval, shearing it off at the base!

Hawthorn's 'Lethal' Leigh Matthews is celebrated for snapping a point post halfway up, but Coleman went one better!

Coleman continued to have an impact for the Dogs in more traditional ways, playing two fine seasons in the hoops before injury brought his career to a close in 1993.

In 1992, Coleman was one of the stars in the Bulldogs' Round 11 win against reigning premiers Hawthorn. That match took his Footscray games tally to 50, making him first player to be 50-plus-game for the separate clubs.

Nearly two decades passed before the second of those came along. Leigh Brown kicked off his AFL career with 63 games at Fremantle, 21 in each of his three seasons as a Docker.

Brown became a Kangaroo in 2004, clocking up 118 games with North Melbourne. In 2009, Adam Treloar's second club – Collingwood – became Brown's third. The 65 games Brown added to his career tally as a Magpie took in three grand finals (two in 2010) and a premiership.

The exclusive club inducted its third member last year when Brad Hill played his 50th game as a Saint. This followed his 95 games for Hawthorn and 54 as a Fremantle Docker.

Adam Treloar will now join Coleman, Brown and Hill as a '50-50-50' player. With luck Treloar will join Brown in an even more elite category by winning an AFL flag at his third club.
