Young midfield prospect Jack Ross will make his senior debut against the Power, coming into the side on the back of impressive recent VFL form.

At 187cm and 87kg, the 18-year-old was taken at pick 43 in the 2018 National Draft, and collected 21 disposals, eight tackles and four clearances in Richmond VFL's Round 1 win over Geelong last Friday night.

The first of Richmond’s 2018 draft class to claim a senior berth, the big-bodied midfielder sees the game well and applies relentless pressure.

Adding to Richmond’s youthful line-up is Shai Bolton and Liam Baker, who have been recalled for their first matches since Round 17, 2018 and Round 22, 2018, respectively.

Connor Menadue has also been added to the side for his first match since Round 20, 2018. Bachar Houli was originally named in the final 22 but didn’t feel ready to play and was replaced in the side by Menadue on Friday morning.

“Bachar trained this week, however, he didn’t feel 100% ready to play, so we felt that it was best to make a change, and look ahead to next week for him," said Richmond General Manager – Football, Neil Balme.

Premiership-winning forward/midfielder Josh Caddy returns for his first senior match of the year after recovering from an ankle injury, and gaining valuable game time in the VFL last week.

The Tigers are also set to be bolstered by the return of defender Dylan Grimes after a week’s suspension.

They come in for Dustin Martin (suspended), Trent Cotchin (hamstring), Jayden Short (elbow), Oleg Markov, Dan Butler and Ryan Garthwaite (all omitted).

Esteemed premiership player and All Australian Shane Edwards will take on the captain duties in Cotchin’s absence, with Grimes acting as vice-captain.
