Livingston boss David Martindale admitted giving Hibs captain David Marshall the middle finger - but pleaded his defence by saying it was in good humour.
But referee Chris Graham didn't see the funny side and sent the boss off to cap off a woeful afternoon for the Lions as they went down 4-1 in a clash that also saw Jack Fitzwater sent-off while Ayo Obileye, Stephane Omeonga and Shamal George all picked up injuries.
Martindale even said Marshall told him after the game he'd happily submit a statement in his defence should the Lions appeal their gaffer's red card - which came during a VAR check deep in injury-time.
