The International Cricket Council's new forgiving stance on narrowly unsuccessful reviews has come into play for the first time on day three of the first Test between South Africa and Bangladesh at Potchefstroo.
South Africa failed to overturn a decision but did not lose their review as brand new ICC playing conditions now see teams keep a review if the ball-tracking technology's verdict is 'Umpire's Call', used when a decision is deemed too close to overturn.
LIVE SCORES: South Africa v Bangladesh, first Test
Fast bowler Kagiso Rabada appealed for lbw against Tamim Iqbal in the fourth over of the day after Bangladesh, replying to South Africa’s 3-496 declared, had added four runs to their overnight total of 3-127.
After Australian umpire Bruce Oxenford turned down the appeal, the Proteas asked for a review, which showed the ball clipping the outside of leg stump, in the 'Umpire's Call' zone.
Previously South Africa would have lost one of their two permitted reviews but under new regulations which came into effect on Thursday, they kept the review.
The Proteas did however lose a review in Rabada’s next over when a reverse-swinging yorker struck Tamim on the boot before going off his bat for a run.
Again the hosts challenged Oxenford’s not-out decision but although Tamim was struck in front of the stumps, the ball was swinging so sharply that it was shown to be missing the stumps completely.
South Africa did not ask for a review in the same over when replays showed Mominul Haque’s stumps would have been hit by yet another swinging Rabada delivery.
Under the previous rules, captains were allowed two unsuccessful reviews every 80 overs during a Test innings, but in addition to the more lenient rules on 'Umpire's Call' review, teams now do not get their review tally renewed at the 80-over mark.
The new ICC playing conditions also see bat thickness restricted and harsher penalties in place for violent behaviour.
