A disc is deemed to have hit the ground when it contacts the ground and no player had caught the disc prior to the disc contacting the ground, or after the catch, the player loses control and the disc subsequently contacts the ground.After a pull or a turnover where the disc hits the ground in-bounds, if the offence attempts to pick up the disc in-bounds, but fails to pick it up and the disc drops to the ground, that is not a new turnover, unless the offence had full control of the disc prior to accidentally dropping the disc.
