Collingwood have rolled the dice on injury-hit big man Ben Reid for Saturday's preliminary final against GWS at the MCG.
Reid hasn't featured for the Magpies since round 15, but has been named for his 150-game AFL milestone as a replacement for injured forward Jordan De Goey (hamstring).
In the only other change for the Magpies, James Aish was named in place of Levi Greenwood, who ruptured the ACL in his left knee in the qualifying final win over Geelong.
GWS suffered a huge blow on Thursday night when Toby Greene's bid to overturn his one-match suspension at the AFL appeals board failed .
The Giants had originally named Greene in their team, but they replaced him with emergency Lachlan Keeffe after the failed appeal bid.
Small forward Ian 'Bobby' Hill was named in place of star midfielder Lachie Whitfield (appendicitis) in the only other change for the Giants.
Reid's season looked over in July when he injured his hamstring while on the comeback trail from a calf injury.
But the 30-year-old has worked his way back to full fitness in the nick of time, and will play an important role against the Giants.
The punt on Reid is a huge gamble given he lasted just four minutes before pinging his calf in his most recent AFL appearance - a 44-point loss to North Melbourne in round 15.
Geelong made just one change for Friday night's preliminary final against Richmond at the MCG - naming Lachie Henderson in place of the suspended Tom Hawkins.
But whether Henderson plays up forward or in defence remains to be seen.
Coach Chris Scott also has the option of using Harry Taylor in attack, and he'll keep Richmond guessing until the bounce of the ball.
The Tigers named an unchanged team from the qualifying final win over Brisbane, meaning Toby Nankervis and Ivan Soldo will tag team in the ruck against Rhys Stanley.
