The extended squad is in for Richmond's Round 16 clash with Carlton on Sunday at the MCG, with the Tigers naming four inclusions.
As announced earlier this afternoon, 22-year-old intercepting defender Jacob Blight will make his AFL debut against the Blues.
Blight, 196cm, was taken by the Tigers in last month's Mid-Season Rookie Draft from WAFL club Peel Thunder, and has made an immediate impact at VFL level since arriving.
Experienced midfielder Jacob Hopper is set to return from a hamstring injury which has seen the 27-year-old sidelined for the past six games.
Also featuring in the extended squad are young wingman Sam Banks and 19-year-old defender Kaleb Smith, who are a chance to be recalled after both recording 20 disposals and seven rebound-50s in the VFL Tigers' most recent clash.
Out of the squad is Tom Lynch, who will miss at least the next two weeks due to a hamstring strain.
Richmond captain Toby Nankervis will celebrate his 150th AFL game on Sunday at the MCG.
The Tigers will confirm their final Round 16 team on Friday night at 5.00pm AEDT.
The Club will then name its substitute 60 minutes prior to the first bounce on Sunday.
Sunday's game will be broadcast live on Channel 7, FOX FOOTY and Kayo Sports.
