Richmond has added six players to its extended squad for Sunday afternoon's clash with Port Adelaide at the MCG, including a potential debutant.

Powerful utility Mykelti Lefau is a chance to play his first game at the level after being named in the squad of 26. 

The 25-year-old was elevated from Richmond's VFL program last month as a Supplementary Selection Period selection.

Tiger tall Ben Miller could be recalled for his first appearance of 2024 as a replacement option for unavailable defenders Josh Gibcus and Tylar Young. 

Meanwhile, promising young defender Tom Brown could be in line to run out for his second AFL match.

Miller was a standout in the VFL Tigers' practice match win over Carlton Reserves last Thursday, with coach Steve Morris noting his performance as "probably the best game I've seen Ben play".

"I thought he was an outstanding leader of our back six," Morris said.

"He won the ball back for us, he took three contested marks, he had an impact with his big spoils and he used the ball well.

Morris was equally impressed with Judson Clarke, who also features in the squad.

"After an interrupted preparation for the season after surgery on his shoulder, he has started to hit some red-hot form," Morris said.

"His last month of footy has been outstanding."  

Ruck/forward Samson Ryan and wingman Sam Banks could also be recalled to the Tigers' line-up after being omitted for Round 1. 

Coming out of the side is Gibcus, who ruptured his ACL last Thursday night against Carlton, Young, who suffered a concussion during the clash, and Dion Prestia, who injured his hamstring in the game. 

Richmond will confirm its final Round 2 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 FOX FOOTY and Kayo Sports.
