Cape Town - Manchester United are facing a striker crisis after Marcus Rashford sustained a groin injury during the 2-0 defeat to West Ham United on Sunday.
Rashford went off with a groin injury after 61 minutes, compounding the misery of Solskjaer as his fragile side suffered their seventh defeat in their last 15 Premier League games.
United were trailing to Andriy Yarmolenko's 44th-minute goal when the England international limped off, but Solskjaer had no forwards on the bench to turn to and sent on Jesse Lingard as Rashford's replacement.
The Red Devils were without the services of Anthony Martial and Mason Greenwood at the London Stadium because of a thigh problem and tonsilitis respectively.
After the match, the Norwegian gave an update on Rashford's situation and revealed that the player had already been booked in for a scan on the muscle problem.
It looks likely that the 21-year-old will be out until the next international break, which comes after United's next two Premier League games at home to Arsenal and away to Newcastle United.
Solskjaer said: "He has done something to his groin we will have to see how bad he is."
The United boss did have some positive injury news to counter that with it looking increasingly likely that Martial and Paul Pogba could be back in time to tackle Arsenal a week on Monday.
And Greenwood, who scored his first senior (competitive) goal for United in their 1-0 Europa League win over Astana on Thursday, is set to play against Rochdale in the Carabao Cup third-round tie that is next on United's fixture list.
"I reckon Mason and Anthony won't be too far away and have at least Mason ready to play on Wednesday but let's see," added Solskjaer, who also confirmed Pogba was expected to play in that midweek encounter against the League One side.
