In his second year he sprained his ankle and finally, after two seasons of waiting, McIntosh got a game against Adelaide in round 6, 2005. He was not selected for the rest of the year but was an emergency eight times.
In 2007, McIntosh averaged over 15 possessions a game. He was picked in the 40 man All-Australian squad. However, he missed the final cut.
The 2008 season was a terrible one for McIntosh. He ruptured his posterior cruciate ligament against Fremantle in round 12. He made a return later in the season but he could not reach the heights he achieved in the 2007 season. He was offered as trade bait by Dean Laidley, which angered McIntosh.[2] Ultimately he was not traded and had a good 2008 season in which he was considered as a contender for All-Australian selection.[3]
McIntosh enjoyed a strong 2010 season, during which he formed a highly effective ruck pairing with Todd Goldstein. But prior to the 2011 season, McIntosh required surgery on both Achilles tendons,[4] and played just one game for the season. He returned for round 1, 2012, memorably missing a shot at goal after the final siren which allowed opponents Essendon a two-point victory. McIntosh suffered a knee injury in round 7 which eventually required surgery,[5] restricting him to just seven games for the year. In October 2012, McIntosh was traded to Geelong for a second-round draft pick.[6]
McIntosh signed a three-year contract with the Cats, but his 2013 season was ruined by various leg injuries and he failed to play a single game.[7] The 2014 season was a better one for McIntosh, making his Geelong debut in round 1 and going on to play 19 games, including a final. He swapped main rucking duties with Dawson Simpson. But injuries hit McIntosh again in the 2015 season, with further knee and calf tendon problems. He was forced into retirement on 29 July 2015 after an ankle injury.[8]
