Three members of Richmond's 2024 AFL Draft crop will make their senior debuts when Richmond host Carlton at the MCG on Thursday night.

No.1 pick Sam Lalor and key position first-rounders Luke Trainor and Harry Armstrong will be named in the Yellow and Black line-up for the blockbuster Round 1 clash.

Lalor has cleared concussion protocols and overcome a hairline fracture of his jaw suffered in match simulation against West Coast on February 17 to take his place in the side.

Prior to the last-minute injury, the talented 18-year-old had kicked two goals against the Eagles. He also booted another two goals in last Thursday's Richmond match sim, playing predominantly as a forward.

Hailing from Bacchus Marsh, Lalor starred as an inside midfielder, who could impact the scoreboard when moved forward for the Greater Western Victoria Rebels and Vic Country across 2024.

Trainor, Richmond’s fourth pick (No. 21 overall) in last year’s Draft, gets his opportunity in the defensive end after an impressive first pre-season at Tigerland.

The 194cm, athletic 18-year-old impressed in Richmond's pre-season match against Collingwood at Ikon Park, collecting 12 disposals (at 92% efficiency) and four marks in just 40 per cent of game time.

Trainor followed up with a solid performance off half-back in last week's match simulation at Punt Road, including a classy running goal.

Standing at 195cm, Armstrong will take his place as a key target in the young Tigers' forward line on Thursday night.

The Vic Metro and Sandringham Dragons focal point was taken by Richmond with pick no. 23 in the 2024 draft.

After missing the trip to Perth due to illness, Armstrong recovered in time to face Collingwood where his work to lay four tackles and compete strongly in the air was highlighted by coach Adem Yze.

"We looked at some vision from the game against Collingwood and we highlighted some of the things he did without the ball and some of the contests . . . What we do value is the contest he’s providing," Yze said.

Lalor, Armstrong and Trainor will debut in front of what is expected to be a bumper crowd at the ‘G on Thursday night.
