The Manchester United goalkeeper withdrew from the Euro after England’s first win over Croatia due to a tear in the buttocks and Henderson said the injury was first suffered in the victory 3-1 against Burnley on April 18.
Henderson, 23, returned to training earlier this month but was unavailable for friendlies with Derby County and Queens Park Rangers, and was not deemed ready to play against Brentford.
United had planned to play Henderson in their scheduled friendly at Preston today, but the game was called off after United reported positive tests for Covid-19, only to run further tests and found no positive cases in the first team.
“Obviously I was devastated back then, when I had to withdraw from the squad,” he told United’s website. “But I had an ongoing injury in Burnley’s game last season (April) and I was really struggling.
“I had a really bad left hip and needed to be taken care of and I had a CT scan when I left for England. I tried to stay silent because obviously I wanted to be involved and not miss a game towards the end of last season, I just wanted to keep the momentum going.
“For me that was something I had to sort out, so taking a break and coming to my senses, then coming back early and sorting everything out so I’m ready for the season is something I look forward to. “
David de Gea is due to return to United training next week and United signed substitute goalkeeper Tom Heaton earlier this summer.
