Manchester United limped into the Carling Cup final on Tuesday night, with Rafael ruled out for a month and Anderson taken to hospital for x-rays on a serious-looking leg injury.
United's 4-2 second-leg triumph over Derby County confirmed a Wembley date - almost certainly with Tottenham Hotspur - on March 1. But it is Saturday's meeting with Spurs in the FA Cup that will concern Ferguson most as he copes with a massive injury crisis.
Aside from Anderson, carried off after the final whistle, and Rafael - who hobbled off just before half-time with a torn hamstring - Nani, Gary Neville and Ryan Giggs all failed to complete the full 90 minutes.
While Jonny Evans did get to the final whistle, he was limping badly with an ankle injury.
"There are probably six or seven of them who have picked up injuries," confirmed Ferguson. "It has been a bad night in that respect.
"We finished with 10 men. But it was effectively nine, because Jonny was in great discomfort. We will just have to see what happens now."
