Manchester United will be without goalkeeper Dean Henderson for their training camp in Scotland as he continues to recover from coronavirus.
Henderson tested positive a few weeks ago but is still feeling unwell, so has not travelled with the rest of the squad this week.
A club statement released on Monday read: "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.
"He is expected to be training again soon."
The 24-year-old was forced to withdraw from England's Euro 2020 squad with a hip problem, but has fully recovered from that injury.

It is unclear at this stage whether the United academy product, who made 26 appearances last season, will be fit enough to start in the first Premier League game of the season against Leeds on August 14.
David de Gea, who rivalled Henderson for the No 1 goalkeeper spot last season, has joined up with the rest of the squad in Scotland after his extended summer break following his participation in Euro 2020 with Spain.
Meanwhile, new signing Tom Heaton and Lee Grant have made appearances in between the sticks in United's other pre-season friendlies.
United's final pre-season friendly is against Everton at Old Trafford on Saturday.
