Manchester United have not set a return date for Dean Henderson as he continues to suffer following Covid-19.
Henderson tested positive following his return to training on July 13 and the goalkeeper has missed the entirety of United's pre-season programme.
The 24-year-old has been lined up to start the season but David de Gea is expected to be in goal for United against Leeds United in their Premier League opener next week.
Jesse Lingard tested positive since he returned with the United squad from their training camp in St Andrews on Thursday and he is a doubt to be available against Leeds.
"Jesse feels okay, hopefully it'll stay that way," Solskjaer said. "But when you get a positive test you've just got to isolate even if you feel well.
"Dean was positive early on. He's negative in his testing but he has not felt as energised and sharp as he normally has done, so he still feels fatigued and is feeling the after-effects.
"You never know. You've seen so many effects of this virus, he's still got a few days to rest and then we'll check up on him."
With Henderson likely to be sidelined against Leeds, new signing Tom Heaton could be on the bench.
