Good pace from Mark Wood as he digs one into the pitch which hits David Warner in the midriff. Warner is hurt by the blow but quickly shrugs it off.
He'll have a bruise there later.

Andrew Morris: Is there an unluckier bowler than Mark Wood? His performances sort of sum up England's fortune - or lack thereof - this series.
Aus 44-0published at 10.5 overs
Ollie Robinson spears one into into David Warner's pads and England appeal. Ben Stokes is urging Joe Root to go for a review but the skipper declines. It looked like it was sliding down leg.

Just under 30 minutes left in the day. Can England claw something back on what has been a thoroughly miserable and depressing day for English cricket so far?
Ollie Robinson dishes up a tasty short one which just sits up and David Warner efficiently pulls it for four before remarking his guard.

If you're just waking up on this gloomy Boxing Day morning, you may want to go back to sleep.
You guessed it, England's batting collapsed again. They've been bowled out - yes, already - for 185 having lost the toss and been put in to bat.
It was a bowl first day, but not a 185 all out day. Pat Cummins set the tone with three wickets before lunch before England continued in the same pattern of gifting their wickets away.
Zak Crawley's return to Test cricket saw him make just 12 while Haseeb Hameed registered England's 50th Test duck of 2021.
Joe Root made yet another half-century, Stokes and Bairstow attempted a counter-attack but ultimately, ill-discipline cost them again.
England's bowlers are once again trying to dig their batters out of a hole but it's not started brilliantly with David Warner racing along to 27 as they haven't managed anything close to Australia's level of consistency.

How long can Silverwood stay on after this? Poor preparation and poor performance has seen us win 4 in 15 in 2021!

Former Australia captain on Test Match SpecialMark Wood is really cranking up the pace. He's touching 95mph. I'd love to see him bowling with 350 runs on the board to play with.

Mark Wood is doing his best to unsettle David Warner.
The Aussie opener nervously dangles his bat out to a ball outside off stump from round the wicket.
Next ball climbs into Warner but he is able to fend it off to mid-wicket to get off strike.

Ollie Robinson back on after a change of ends. Joe Root is trying everything to get this first breakthrough.
Nothing to really worry Marcus Harris or David Warner so far, though.

Aus 33-0published at 8.0 overs
David Warner chops Mark Wood into the ground behind square as he uses the pace of the ball to pick up another boundary.
Next ball is a vicious delivery from Wood and catches the shoulder of Warner's bat but flies over the slip cordon for a successive four.
Australia getting all the breaks.
Aus 25-0published at 7.4 overs
A beleaguered James Anderson draws a deep breath then sighs, a despondent Joe Root scratches his brow and a miserable-looking Mark Wood traipses back to his mark with his head down.
England's body language is not exactly inspiring here.
