Important Richmond defender Dylan Grimes remains in the frame to take on the Brisbane Lions in this Sunday's season-shaping MCG clash after being cleared of serious damage to his ankle.

Grimes sent a scare through the Tiger camp when he went down with what looked a potentially serious injury during the third quarter of Richmond's thrilling win in the wet against West Coast on Sunday.

But fears that Grimes could be sidelined for the rest of the season like defensive partner Alex Rance have been allayed, with the Tiger avoiding scans on what the club is calling a rolled ankle.

Grimes returned to the field, albeit hampered, against the Eagles, and remains optimistic he will be available to confront the Lions.
