England have ruled vice-captain Ollie Pope out for the remainder of the Ashes after the top-order batter succumbed to a dislocated shoulder.
Pope hurt his shoulder in two separate incidents in the dramatic Lord's Test, after initially going down on day one fielding a ball.
He was then ordered to return to the field in Australia's second innings, or else not be able to bat any higher than No.7 in England's fourth-innings chase.
Pope's injury is likely to mean Dan Lawrence will be called into the hosts' team for Thursday's Headingley Test as the only reserve batter in their squad.
England did have the chance to call up wicketkeeper Ben Foakes and make Jonny Bairstow a specialist batter, but have opted against it.
Lawrence has played 11 Tests for England, and averaged 29.
"Dan's in good form as well, he got 150 for Essex in the last championship game," England star Joe Root said.
"He's in a good mood, in good spirits, which is always good when you've got guys on the periphery and are next in line scoring runs and feeling good within their own game.
"You've seen a glimpse of what he can do in Test cricket, he scored a brilliant 91, he looked nailed on for a hundred in Barbados.
"He's got that steeliness about him that he wants to succeed at this level."
Pope's injury could prompt Root to move up to No.3 in the order, having not batted there since his struggles in the West Indies last year.
The former captain averages 39.67 batting at No.3 compared to his career marker of 50.43, while being limited to four centuries in 59 innings in the position.
"It's not my call anymore, thankfully," Root said.
"It's a big blow, Ollie's been phenomenal for us the last 18 months. He's stepped up as vice-captain of this team.
"The more responsibility we've given him, the more we've gotten out of him as a player and as a leader within the group. He'll be a big miss for us."
