Manchester United's victory over Derby in the Carling Cup semi-final was marred by four new injury setbacks for Sir Alex Ferguson's side.
Young right-back Rafael da Silva limped out of the action in the first half with a hamstring injury before centre-back Jonny Evans aggravated an existing ankle problem after the break.
Nani limped from the field in the closing stages before midfield colleague Anderson was stretchered off after the final whistle after appearing to damage his ankle in an innocuous clash with Giles Barnes.
Ferguson confirmed Anderson will undergo an X-ray on his problem to determine the extent of the damage and expects to be without Rafael for around three weeks.
Evans is expected to be back in action within a week, which will be a welcome relief for the Red Devils with Rio Ferdinand currently sidelined with a back injury.
When quizzed on Anderson's injury, Ferguson told Sky Sports: "He's going to have to go for an X-ray, there is some damage, we don't know exactly what.
"We got a few injuries tonight, it's been a bad night for us that way."
Ferguson was able to shed more light on Evans' problem, with the centre-back forced to hobble on as all three substitutes had been used.
The Scot said: "He (Evans) has had a recurrence of his ankle injury which has been troubling for a few weeks now, but hopefully he'll be OK in a week's time."
And on Rafael, he added: "It's a hamstring injury, he'll be out for a few weeks."
Goals from Nani, John O'Shea and Carlos Tevez put United in control before the interval, but Derby responded well after the break with Giles Barnes' penalty giving them hope.
Cristiano Ronaldo responded with a spot-kick of his own and there was still time for Barnes to find the net again with a superb free-kick before the final whistle.
Ferguson confirmed that he will be using his youngsters again in the final after they secured his 14th domestic final appearance.
He added: "They will be playing in the final. I think that the important thing is to find out their temperament, and they've all proved that again.
"I think Wembley is a special place, our record in going to finals at Wembley is terrific.
"Just being there is always a great occasion, but you always want to win them because that's the only way you can enjoy it."
