Australia opener David Warner posted his 21st Test century in dramatic fashion on Boxing Day.
Struggling through the 90s at the MCG on Tuesday, Warner skied a delivery from England debutant Tom Curran and was caught on 99.
As the frustrated left-hander walked off and England celebrated a crucial wicket, replays showed Curran had overstepped, leading to Warner's return.
Warner flicked the next ball off his hip to bring up his 100 in dramatic style, capping what had been a tough start to the fourth Ashes Test for England.
Australia were 131-1 at the time after Steve Smith elected to bat on a flat pitch.
