RICHMOND has upgraded rookie Jayden Short to its senior list ahead of Friday night's clash against Collingwood at the MCG.

Short has been elevated as a replacement for injured midfielder Reece Conca and is now in contention to face the Magpies.

Richmond is looking to replace injured half-forward Shane Edwards, with Short throwing his name forward after an impressive pre-season that has gone under the radar.

"He did a lot of work running in the off-season, and he came back and ran some PBs [in the pre-season]," senior development coach Mark Williams said.

"At training, he's been a standout with his tackling, his chasing and goalkicking.

"He's probably improved as much as any of our young players from last year to this year."

Short was recruited by the Tigers with pick No.11 in the 2014 NAB AFL Rookie Draft, and spent 2015 in the VFL before an ankle injury ended his season.

He has been used forward and in the midfield, making him a likely replacement for Edwards, who will miss one match with a hand injury.

Conca was placed on the Tigers' long-term injury list ahead of round one and is not expected to return from a serious hamstring injury for five to seven weeks.
