Shane Mumford is set to begin his AFL comeback with the Giants under suspension, with a two-match ban likely as a result of the league's investigation into the video of the ruckman snorting a line of white powder.

Greater Western Sydney will hand down a provisional suspension and fine to Mumford, who is also expected to receive a drug strike under the AFL's illicit drugs code and will undergo counselling.

A two-match ban is the probable punishment, which is expected to satisfy the AFL. The suspension can only take effect once Mumford is a GWS player.

He spent this year as a member of the club's coaching panel, with the Giants proceeding with their plan to bring him back, as a delisted player, to bolster their ruck stocks.
