Richmond will miss a trio of key players against Collingwood as the Tigers seek radical improvement from their round-one AFL clash with Carlton.

Coach Damien Hardwick said Shane Edwards (hand), Brett Deledio (foot) and Ivan Maric (back) won't turn out for the Friday night match.

The Tigers edged Carlton in their season-opening clash but Hardwick said they'd reviewed the match as if it was a loss given their slow start to the AFL season.
