However, replays confirmed the bowler had overstepped by a narrow margin, and BlIzzard went on to smash the free hit for six and the following ball for four.
With that 18th over ultimately costing Philander 24, the Australian side were back in the game and Blizzard went on to finish unbeaten on 78 from 48 deliveries as the Hurricanes won with an over to spare.
It was a harsh blow to the Cobras given that they had done a lot of things right.
Richard Levi put a frustrating 2013/14 campaign behind him to crunch 42 from 30 balls in his first outing of the new season as the Cobras scored 62 for two in the power play - the highest power play total in the competition so far.
And, although wickets fell regularly in the middle period, most of the batsmen contributed something to keep the scoreboard ticking over before Philander and Robin Peterson added an unbroken 52 for the seventh wicket from just 24 balls.
Peterson’s ingenuity was a source of constant frustration for the Hurricanes at the death as he scored 25 from 14 balls, while Philander’s power hitting brought him 32 from the same number of deliveries as the Cobras finished on 184 for six.
Ben Dunk’s 54 ensured that the Hurricanes chase was on track as they reached the halfway stage on 90 for one, but Sybrand Engelbrecht struck three times to record figures of 3 for 20 in four overs and change the course of the game.
However, Philander’s unfortunate no-ball proved to be another turning point in a tight match, the result of which leaves the Cobras with two defeats in two games and an uphill struggle to qualify for the semi-finals.
Adding to their difficulties is an injury to off spinner Dane Piedt, who left the field after sending down just 11 deliveries when he picked up a shoulder problem whilst fielding off his own bowling.
