Stuart Broad has admitted that England "mentally switched off" on day two of the second Ashes Test as they fell to 85-4 in reply to Australia's 566-8 declared.
Mitchell Johnson took two wickets in seven balls on a slow Lord's pitch, with Alastair Cook and Ben Stokes steadying the England chase after losing their first four wickets for just 30 runs.
Speaking to Sky Sports News, Broad said: "We mentally switched off for 20 minutes, which in Test cricket you can't afford to do. Credit to our bowlers on coming back today - we fought back well.
"They bowled really well tonight. When you've got a lot of scoreboard pressure and 30 overs to bowl, you can fly in for one spell."
Earlier in the day, Steve Smith hit 215 in what has been a dominant display from the Australians.
