Harry Middleton and Craig Alcock will miss the start of the season after picking up serious injuries in last night’s 2-2 draw with Newcastle United.
A disastrous night on the injury front also saw youngster Joey McCormick dislocate his shoulder and Joe Wright hobble off before half time.
“Three of them are very bad,” said Ferguson after the game.
“Young Joey has dislocated his shoulder and gone to hospital. He’s only just come back from dislocating his other shoulder so he’s understandably upset.
“Harry Middleton will have a scan. It looks like he’s done his knee ligaments and possibly more.
“Craig Alcock will have a scan as well. He’s done his ankle ligaments.
“Out of the four, Joe Wright is probably the one we think will be fine. It’s a recurring injury that he’s had with his toe.
“But certainly the three in the second half look like quite bad ones. There’s no way they’ll be fit for the start of the season.”
He added: “It was a bit surreal because you don’t usually see that in any game let alone a pre-season friendly.
“It wasn’t played like a pre-season friendly which I was pleased about. It was a competitive game.
“Performance-wise I was very pleased with the first half. In the second half it was disappointing to lose a goal to a set piece but we had to dig in because they came on strong.
“Obviously the one thing we don’t want is injuries but we’ve picked up three tonight. We just have to get on with it. It’s part and parcel of the game.
“Hopefully Joe’s all right, because he did well before he came off.”
