Hoskin-Elliott had surgery on February 18, with the Collingwood forward expecting to miss (at most) the opening two games of the season.
However, a recent update claims the 25-year-old will be sidelined until round seven or eight of the season.
In better news for the Magpies, Taylor Adams is in line to return this weekend against the Eagles at the MCG.
Adams has recovered from a tendon injury in his finger, which left him out of the JLT Community Series and the opening two games of the season.
“As long as he completes his training the surgeon has cleared him and we would expect him to be available to play,” Collingwood football manager Geoff Walsh told collingwoodfc.com.au on Tuesday.
Tim Broomhead – who broke his leg in round two last year – will play in the VFL this weekend in his return from the injury.
