Australia captain Pat Cummins has bowled with a pink ball in Sydney ahead of the day-night Ashes Test in Brisbane.
The 32-year-old, who missed the first Test in Perth with a back injury, trained in the nets at Cricket New South Wales' headquarters on Tuesday.

Fellow bowler Josh Hazlewood, currently sidelined by a hamstring injury, made his return in the nets in Sydney but bowled with a red ball, indicating he isn't in the frame to feature at the Gabba.
However, Australia head coach Andrew McDonald has shut down suggestions that Hazlewood will miss the entire series.
"He's working through his first week of rehab," McDonald said. "Once he gets further down the track, then we'll be in a position to communicate [updates].

In the absence of two of their standout pace bowlers, Australia beat England by eight wickets in the first Test, with Mitchell Starc leading the way with match figures of 10-113.
