Pivotal Richmond star Brett Deledio is in doubt for the Tigers' season-opener against Carlton on Easter Thursday after missing a training session on Sunday.
The Tigers' mounting injury woes have been worsened by Deledio's injury, which is understood to be a soft-tissue problem. He has not been officially ruled out of Thursday's MCG blockbuster but it's believed he is also no certainty to play against Collingwood in round two.
Richmond held a family day at Punt Road Oval on Sunday morning but Deledio was absent from the club's open training session.
Deledio's importance to Richmond's side was underlined last year when he missed the early part of the season with a calf injury and lost four of their first six matches.
After a bruising last preseason game Richmond will be without Reece Conca for six weeks because of a hamstring injury, while recruit Chris Yarran has also been sidelined for six weeks after footy surgery.
