Richmond has been dealt yet another blow ahead of its Round 13 clash against the Crows in Adelaide tonight.
Ruckman Ivan Soldo has been ruled out of the match because of a virus, with Mabior Chol coming in as his replacement.
Chol made his debut in Round 23, 2016 and hasn't played since.
The 22-year-old has been in good form in the VFL and was awarded the Sir Doug Nicholls Medal in the VFL Dreamtime match against Essendon last month.
The injury-depleted Tigers will be missing premierships heroes Trent Cotchin, Shane Edwards, Alex Rance, Jack Riewoldt, David Astbury, Toby Nankervis and Kane Lambert, among others.
