Due to the effects of contracting Covid-19, goalkeeper Dean Henderson will miss Manchester United's training camp in Scotland.
The 24-year-old was forced to withdraw from England's Euro 2020 team due to a hip issue, and while he has since recovered, catching coronavirus last month has thrown his pre-season plans into jeopardy.
"Dean Henderson will miss Manchester United's Scotland training camp while he continues his recovery from prolonged fatigue after contracting a COVID-19 infection three weeks ago," said a club statement.
"He is expected to be training again soon."
Following his post-Euros rest, Spain goalkeeper David De Gea rejoined the group at the camp in Scotland on Monday.
Last season, De Gea started 36 games and Henderson 25, although manager Ole Gunnar Solskjaer looked to prefer the latter for the start of the current season.
So far, Tom Heaton and Lee Grant have appeared in United's warm-up games.
