The experienced 24-year-old Uruguayan striker was running alone towards goal when the keeper tackled him just outside his box, hitting him square on the right leg and inflicting terrible damage.
Bueno was immediately attended to by the medical staff, who quickly stretchered him off the pitch and into an ambulance, which took him to the nearest hospital.
Orion, who looked to be slightly injured himself from the challenge, received a straight red card for his brutal tackle.
