Warne faces Lord's censure
The row erupted when Hamsphire thought they had Newman, then on 14, caught behind by Nic Pothas in the fourth over of the day. Led by Billy Taylor, the bowler, the fielding side staged a prolonged appeal, leading to Whitehead approaching Warne, Hampshire's captain, at the end of the over.
The pair engaged in what appeared to be a heated discussion lasting a couple of minutes and which involved a fair amount of finger wagging and gesticulating. The animated exchange reignited several times, both parties returning to the fray just as the debate appeared to be ending.
Alan Fordham, the first-class cricket operations manager for the ECB, acknowledged that he had spoken to Whitehead during the tea interval but refused to comment further - neither would either official.
But Warne, who received three disciplinary points after a clash with Somerset's Peter Bowler last season, and Whitehead were believed to have been called together at the close of play to try to resolve their differences.
To rub salt into the wound, Newman went on to score a hundred, although when he was finally dismissed for 111 immediately after tea there was hardly more than a splatter of applause as he returned to the pavilion.
