Ole Gunnar Solskjaer says injury forced Romelu Lukaku to miss Manchester United's friendly with Kristensunds.
The Belgian has not participated in any of United's five preseason friendlies, with speculation he could join Inter Milan or Juventus this summer.
But Solskjaer insists Lukaku has not been physically ready to play in matches.
"He got injured. It was best for him to stay home. He wouldn't have been able to play," Solskjaer said.
"Hopefully he might be able to train in the next couple of days, Rom. Let's see what happens.
"You never know what happens in football. He's not been able to train but he's not been that bad that we had to send him home, we still had hope he was going to be fit to play in Australia, Shanghai and Singapore. But, for this short trip, there was no point bringing him."
