There are photos of before during and after the ball being passed, and he is offside in all 3. So their next claim is that someone in the SFA photoshopped it to make it look like he was offside.
Remember, it is all a Cafflick conspiracy against the peepul, do they will do absolutely anything to ensure that the Tims win. This includes awarding only 1 penalty against sevco in nearly 120 league games, failing to send off Sterling, failing to give a penalty & red card against Tavernier and correctly not giving a penalty to Sellick!
