Making his first appearance since the end of January following a calf injury, Holmes lasted just 25 minutes after picking up a separate injury when tackling an opponent which has resulted in ligament damage.

Warnock said: "Duane is going to be out for the season now, I'm afraid. He's gone to see a specialist today. There's quite a lot of damage done.

"He blocked a shot that was going across, so he's had ligament damage and a tendon problem. I also think he's a little chip on his ankle as well.

"He's got everything wrong, the poor lad. And he has done so well to get back fit since I have been here. It's a shame, but these things happen.

"You have just got to be mentally strong to get back into the reckoning next season. It's is disappointing, but that is how football is.

"You are up one minute and down the next and he's going to have to do another rehabilitation to get himself back."

Meanwhile, Warnock - whose side visit Watford on Good Friday and welcome Blackburn Rovers on Easter Monday - has confirmed that striker Martyn Waghorn is unlikely to feature over the Easter programme with an.

"But he just felt something as he was finishing in training. I don't think I want to rush him and we might have to give him a rest over this weekend and make sure he's right for the final games.

"Poor Anthony has one thing after another really. He's a little bit of a knock as well and it will be difficult for me to get him involved between now and the end of the season as other lads are doing so."
