Today I heard on news about new handball rules by IHF that will be applied in Olympic tournament. I googled a bit about it and found this:
1. Goalkeeper as a player: The goalkeeper may be used as a seventh field player.
2. Injured player: An injured player should leave the playing court after receiving medical care on the court and can only re-enter after the third attack of his team is complete.
3. Passive play: After showing the forewarning signal the team forewarned has a total of 6 passes to shoot on goal.
4. Last minute: In Rules 8:5, 8:6, 8:10c and 8:10d, the wording “last minute of a game” should be replaced by “last 30 seconds of a game”.
5. Blue card: The referees have a blue card in addition to the yellow and red ones to provide more clarity regarding the disqualification of a player. If this card is shown, a written report will accompany the score sheet and the Disciplinary Commission will be responsible for further actions.
