South Korean K League rivals Jeonbuk Motors were 2-1 down to Seongnam on Wednesday evening when a Seongnam player went down injured in his own box. After the stoppage, former Middlesbrough striker Lee Dong-Gook attempted to return the ball to the Seongnam keeper, but struck it a little too hard and ended up planting a long-range screamer in the top-right corner. It might have been an accident, it might have been unsporting behavior, but we certainly can't remember Dong-Gook doing anything like that at either end of the field for Boro.
After a few minutes of bickering, Jeonbuk Motors reluctantly agreed to concede a consolatory goal at their own end. Rather than let a Seongnam player run through and score unopposed, however, they made the curious decision of letting their own goalkeeper put it into his own net from a few yards.
The match finished 3-2 to Seongnam, meaning the keeper's deliberate OG decided the match.
