England spinner Jack Leach out of first Test due to concussion symptoms, Matt Parkinson to debut

England spinner Jack Leach has been ruled out of the first LV=Insurance Test against New Zealand at Lord's due to concussion symptoms with Matt Parkinson to debut as his replacement.

Leach took a heavy fall on the boundary chasing a ball in the sixth over of the game on Thursday and has now been withdrawn from what was his first home Test match since 2019.

England soon confirmed that Lancashire leg-spinner Parkinson would join the camp and the 25-year-old linked-up with the side late on Thursday afternoon after travelling down from Manchester.

Parkinson becomes England's first concussion substitute in Test cricket.

There was no other spinner in the initial squad - seamer Craig Overton and uncapped batter Harry Brook were the other members of a 13-man party - and teams must bring in a like-for-like player when it comes to concussion replacements.

Parkinson was presented with his cap by England spin coach Jeetan Patel.

Parkinson has been in previous Test squads without making his debut, while he has made nine white-ball appearances, taking 11 wickets across five ODIs and four T20 internationals.

He has taken 126 wickets in 37 first-class matches at an average of 23.84,with four five-wicket hauls and a best of 7-126.

An ECB statement read: "Jack Leach has symptoms of concussion following his head injury whilst fielding. As per concussion guidelines, he has been withdrawn from this Test."

A later update said Leach would have "a graduated return to play with a minimum period being seven days, in accordance with concussion guidelines".

That means Leach is a doubt for the second Test at Trent Bridge from next Friday (June 10).

The three-Test series concludes at Clean Slate Headingley from June 23.
