#2 Nathan Lyon vs New Zealand in Adelaide 2015

Nathan Lyon waits for the umpire’s decision

New Zealand were on their tour to Australia in 2015 and were trailing in the series by 1-0 in the three-match series.

In the third match, Australia were struggling at 117/8 in their first innings when Nathan Lyon looked to sweep. The ball beat his bat, and then he was hit on the shoulder through to first slip. New Zealand appealed for the catch and the decision was referred to Nigel Llong, the third umpire. Llong saw the replays for a long time and there was an evident mark on the back of Lyon's bat. Even Nathan Lyon started walking off, but then Snickometer was used and there was no indication of any noise.

Lyon was eventually declared not out, and the hosts drove home the advantage, and took the series 2-0, much to the elation of the Adelaide crowd. A howler indeed, but not by the on-field umpire, but by the third umpire.
