The club is hopeful both Walker and Cook will be fit to play Sydney next week.

In good news for the home side, skipper Jordan Dawson has overcome a foot issue and has been named to face the Tigers.

Ruckman Kieran Strachan has been recalled for his first senior game in more than two years, while the Crows have also named Ned McHenry and Will Hamill alongside debutant Billy Dowling.

The Tigers have named Koschitzke for just his fourth senior game of the season, replacing the injured Mykelti Lefau up forward, while gun trio Shai Bolton, Tim Taranto and Dion Prestia all return.

Dustin Martin has been managed ahead of his 300th game next week, while Marlion Pickett (calf) and youngster Kaleb Smith (omitted) are out.
