Richmond's rebels have given president Clinton Casey until Tuesday to stand down from the AFL club or face a leadership challenge.

Rebel member Michael Pahoff and alternate president Brendan Schwab have both vowed to present petitions calling for a spill of the board if Casey does not stand aside on Tuesday.

Both parties have collected petitions with the required signatures of 100 members calling for Casey's board to stand down.

Under the Tigers' constitution, just 100 signatures are needed for the club to hold an extraordinary general meeting (EGM), which would likely move a motion of no confidence in Casey and his board.

Pahoff would present his petition on Wednesday if Casey did not act on Tuesday, while Channel Seven reported Schwab's challenging group had given the president the same deadline.

Seven reported Schwab's ticket also wanted some of its group put on the sub-committee searching for a replacement for outgoing coach Danny Frawley.

Richmond management had opposed the organisation of a petition, arguing it will cause more damage than good.

Casey said the club would try to ward off an EGM by contacting the members who had signed the petitions and ask them to withdraw their support for the rebels.

But Pahoff Monday insisted he had legal advice the board could not avoid an EGM and subsequent elections once the petition had been presented and vetted.

Richmond football director Greg Miller Monday said the board could not act until it learned precisely what any petition was calling for, but he reiterated Casey's claims any challenge would cause more harm than good.
