England spinner Jack Leach had to be withdrawn from the first Test against New Zealand before lunch on day one.

Leach, playing his 23rd Test in England's first match since Ben Stokes was named captain, had not yet had the opportunity to bowl when he set off in pursuit of a Devon Conway drive off Stuart Broad in the sixth over.

The Somerset man did superbly to prevent a boundary with a lunge towards the rope, but he appeared to land awkwardly on his neck as he tumbled forwards.

Leach did not immediately get up and required treatment, exiting the match but able to walk himself back to the dressing room.

An ECB statement soon revealed: "Jack Leach has symptoms of concussion following his head injury whilst fielding.

"As per concussion guidelines, he has been withdrawn from this Test. We will confirm a concussion replacement in due course."

England had already reduced New Zealand to 2-2 at the time of Leach's injury, and the Black Caps were still struggling on 22-4 as news came of his withdrawal.
