However, there’s better news for the injury-hit Crows with defender Daniel Talia cleared to play against St Kilda at Etihad Stadium on Saturday.
Talia hyperextended his knee, but finished the game on the field.
Crows GM of high performance, Matt Hass, told the dlub’s website that scans showed Crouch had suffered a minor strain.
“It’s a pretty straightforward hammy, low-grade,” Hass said.
“We expect him to be out for about the 21-day period.”
Adelaide is hopeful that a nine-day break between games will allow Rory Sloane and David Mackay to play against the Saints.
Sloane suffered a foot strain against Richmond, but Hass says scans showed there was no major structural damage.
Mackay suffered concussion in a clash with Tiger forward Josh Caddy but has “passed the initial test” under the concussion protocol.
“He’s passed the initial test and he’s commenced running, so all things look really positive,” Hass said.
“He just needs to tick a few more boxes as far as the medical side of things go, but we’re hopeful (he’ll be available) for St Kilda.”
