Controversial Perth defender Chris Billings is at risk of deregistration after being suspended for the second time this season.
Two years after Billings was reported or investigated eight times in 15 matches, resulting in a two-week ban and two reprimands, he has been found guilty of rough conduct and banned for today's match against Peel.
A third guilty verdict this season would trigger the WAFL rule that makes deregistration a possibility.
WAFL rule 6.1.7 says a regis- tration may be terminated for "excessive" tribunal appearances, and that: "Three guilty verdicts in one season would be excessive."
The WAFL Tribunal suspended Billings for one game for felling Subiaco's Brad Stevenson behind the play in last Saturday's game at Kalgoorlie.
Stevenson left the ground under the blood rule, but returned to play out the match.
Billings accepted a two-week ban in his comeback match this season for rough conduct against Claremont's Brendan Lim.
The tribunal cleared him of a rough conduct charge against Aaron Jetta, of Swan Districts, in a round-five reserves match.
Billings, 26, walked away from the WAFL last year in reaction to his 2012 season when his on-field behaviour forced WAFL manager Cam Knapton to warn him that he was at risk of deregistration.
The matters that came to the attention of the tribunal in 2012 included a clash with West Perth's Alex Elisseou, who was left with a broken jaw and has not played league football since.
Billings played for Donnybrook in the South West Football League last season.
