Pakistan´s Mohammad Abbas (R) celebrates taking the wicket of England´s Jos Buttler on the fourth day of the first global Test match between England and Pakistan at Lord´s cricket ground in London on May 27, 2018.
Somerset off-spinner Dominic Bess will make his England debut in the first Test at Lord's.
Babar was taken to a hospital for a scan which confirmed he would not be able to get back on the field at Lord s or indeed take part in next week s second Test at Headingley.
"With Dom Bess, it was like Joe Root walked back out, with his back foot punches and cover drives, " Buttler added.
The pair had put on 125 by the close of play and realistically need to bat for at least another full session to concern the tourists, who will still expect to win the match and take a 1-0 lead in the two-match series. "He's got a great character and he really showed that", added Buttler, who started his career at Somerset before moving to Lancashire. He is the wall that is standing between a humiliating defeat for England or a historic comeback for them in the first Test.
But, in truth the damage had always been done by a pair of top-order slumps that saw England, so often dominant in early-season home conditions, dismissed for 184 in their first innings before declining to 110 for six second time around.
Even Cook, though, was found wanting for his dismissal.
Cook equalled former Australian captain Allan Border's world record of 153 Test appearances in succession. Just before lunch, left-hander Mark Stoneman (9) rocked back to a delivery from legspinner Shadab Khan, only for the ball to keep low and spin into the stumps.
USA crude stockpiles rise unexpectedly in week
Brent crude futures slipped 23 cents to settle at $79.80 a barrel, while US crude lost 36 cents to $71.84 a barrel. Oil prices had a "swift reaction today to the musings by OPEC to potentially add more supply to the market".
Pakistan were soon in the wickets with Cook looking on as the other three members of England's top four all fell in single figures.
It was the exit of Malan, who saw a piece of his helmet fly off after turning away from a Hasan Ali bouncer, that sparked the slump.
England has been prone to batting implosions in recent years and another arrived on a warm afternoon at Lord's, sparked by a superb catch from wicketkeeper and captain Sarfraz Ahmed to remove Malan.
Ben Stokes unfurled a few trademark attacking strokes in his 38 but he was trapped lbw by Abbas following a review and England's last five wickets crumbled for the addition of 16 runs straight after tea.
Two balls later, Amir shaped a ball through the gate as Bairstow was beaten all ends up.
But instead Stokes (nine) carelessly turned Shadab off his pads to midwicket.
This was his 40th half-century at this level but there was no 14th Test hundred as Root fell lbw to Abbas for 68. Jos Buttler, recalled as a specialist number seven, was unbeaten on 13.
Bess ended proceedings in style by driving Amir for four off the last ball of the day.
