United have confirmed that their academy star has been playing with an injury for the past few months and the problem now requires attention.
A club statement read: “Manchester United striker Mason Greenwood has withdrawn from the provisional England Euro 2020 squad, in order to recover fully from an underlying injury that also kept him out of the Under-21 European Championship in March.
“Mason’s club appearances were managed carefully to maintain his availability through the intensive 2020/21 Premier League and Europa League schedules.
“I would have him in,” Shearer said before United confirmed the cruel injury blow. “He probably wouldn’t start the first couple of games but if you need a goal late on then he would be a great option to throw on.
“Having those extra three [places in the squad] might help someone like Greenwood get into the squad.”
Greenwood is not the only Manchester United player who has had to digest difficult news.
The Athletic are reporting that Jesse Lingard has been cut from Southgate’s squad ahead of this evening’s announcement.
Lingard has performed excellently on loan at West Ham where he hit nine goals in 16 matches since arriving in January.
Yet despite forcing his way back into Southgate’s thinking, Lingard is now set to miss out on representing the Three Lions at a second major tournament.
The attacker was one of England’s standout performers at the 2018 World Cup in Russia, where he scored a stunning strike in the 6-1 win over Panama.
Southampton’s James Ward-Prowse is also set to miss out despite playing every minute of the past two seasons.
