"It's what we feared; he's ruptured his anterior cruciute and will miss the rest of the season," Bruce said of Willems, who broke down in victory over Chelsea.
"We've had bad news on Dummett too, it's not looking so good on him as well. It looks as if he's probably ruled out for the season as well with a tendon injury in his leg.
"So it's been a bad weekend in that respect. We wish them well in a hopefully speedy recovery."
