Cummins bowled a short ball that appeared to catch Jaiswal’s glove on the way through to wicketkeeper Alex Carey.
Umpire Joel Wilson, responsible for the infamous not out LBW decision of Ben Stokes off Lyon in the Headingley Test of the 2019 Ashes, was not convinced.
Australia reviewed and replays showed a deviation of the ball off the bat, even though there was no spike on Snicko.

When the 15th and final session of this engrossing Test began, India required 228 runs to win from 228 balls with seven wickets in hand.

Sydney cricket fans have had their fair share of dead rubbers and fixtures devoid of real meaning over the past two decades but have good reason to be excited at what is in store on Friday.
The last time two teams went to Sydney with a trophy still up for grabs in the last fixture of a multi-match series was in 2004 against India, during Steve Waugh’s final Test series. Even then, India made over 700 in the first innings of what was a dull and drawn match.
Cricket Australia is expecting sellouts for the first three days of the SCG Test.
