The Aussies put the brakes on India's batting effort on day two, with Lyon starring on figures of 4 for 67. India still trails by 52 runs with plenty of work to be done in the days ahead.
Lyon has faced criticism throughout his career, but has been excellent on this tour. After play on day two, he shed some light to Grandstand as to why.
"You've got to believe, if you don't believe it's a bloody long day out there, I can tell you that," Lyon said.
