Morris was charged with a level two rough conduct offence against Collingwood’s Jamie Elliot, during the second quarter of Saturday’s match at the MCG.
His place in the side could go to Nick Vlastuin, Richmond's top pick from last year's National Draft (No.9)
"He's in the mix, there's no doubt he's been in the mix for quite sometime," Tigers' coach Damien Hardwick said of Vlastuin on Richmondfc.com.au.
Hardwick added that key defender Troy Chaplin was in doubt after suffering a second concussion in three weeks against Collingwood last Saturday.
