Didak was drafted by the
Collingwood Football Club with the 3rd pick in the
2000 AFL draft, and in
2001 he made his AFL debut against the
Kangaroos at the
Telstra Dome in Round 7, gathering 10 possessions. He managed to
kick a goal with both his first kick and first disposal. He played five games in total in 2001. In 2002, Didak earned an
AFL Rising Star nomination. In 2003, Didak enjoyed his best season to date. In the Qualifying Final against Premiership favourites the Brisbane Lions, Didak came on in the last quarter and kicked two goals to win the match. In 2005, Didak's season was disrupted by injuries and problems. He had knee surgery during the pre-season, setting him up for his first game on
ANZAC Day against
Essendon. His injury had an effect upon his performances. Having had minor issues since the mid-year break, he was suspended in Round 14 for two matches and after returning from that, he injured an ankle. When he returned in the next week, he lasted only 20 minutes, before suddenly fainting on the ground with an irregular heart beat. In 2006 Didak was awarded the
Copeland Trophy as the best and fairest
Collingwood player for 2006. Didak was awarded All-Australian selection for the first time in his career. In 2010, Didak enjoyed his career's best season, winning the club goalkicking with 41 goals and earning All-Australian selection. Didak placed 4th in the club's Best & Fairest, and was a hero of Collingwood's 15th premiership. Didak started off 2011 strongly in a dominant Collingwood side; however, he began to succumb to injuries, which became a common theme until he was delisted at the end of the 2013 season after 13 seasons. == Post-AFL career ==
