Richmond could welcome back tough defender Nick Vlastuin for Sunday’s twilight clash with the Crows at Adelaide Oval.

Concussion symptoms kept Vlastuin out of the Tigers' Anzac Day eve clash against Melbourne on Monday, but he’s expected to recover for Sunday’s trip to Adelaide.

The 23-year-old missed back-to-back matches due to a concussion last year.

Richmond tall Ben Griffiths also suffered a concussion while playing in the VFL on Saturday and won’t be considered for selection this week. It’s the forward/ruckman’s second concussion this season.

Midfielder Anthony Miles was Richmond’s senior emergency last round and could come under consideration given his recent VFL form.

Athletic tall Mabior Chol has also found strong VFL form and booted three goals in the VFL last weekend.

Fellow forwards Ben Lennon and Sam Lloyd are also in the mix should Richmond choose to bolster its attack.
