Two bouncers per over
Bowlers are allowed to deliver two bouncers per over in Tests and one-day internationals, and one per over in Twenty20 internationals, with similar rules applying in senior domestic cricket. Earlier only test cricket used to witness two bouncers per over, but later ICC changed that rule to allow the bowlers to unleash two bouncers per over in the ODI format also. With this rule, Bowlers got the chance to tactically drive the batsman back on to his back foot if he has been freely playing front foot scoring shots and hammering the bowlers with all guns blazing.
