Wales back-rower Ross Moriarty has suffered what appears to be a serious knee injury in the Dragons' clash with the Sharks.
As the game approached the half hour mark, the Welsh side lost ball at their own lineout and it led to Phepsi Buthelezi charging at the Dragons line.
Moriarty, who had shown up superbly in his first game back since the Six Nations, came up to meet him but got himself in an awkward position during the collision.
