KSI's win over Joe Fournier is no more -- 'cause just days after the businessman/boxer filed an appeal claiming he was illegally elbowed, not punched, the boxing commission overturned the victory.
KSI vs. Fournier is now officially a "no contest."
Of course, the two met in the ring at the Misfits Boxing event at the OVO Arena Wembley ... where each fighter traded punches for two rounds before KSI landed the final blow to Fournier's jaw.
ONE HIT ELBOW
At first, it looked like KSI landed a clean punch .
