However Jarrett has returned to the club in determined mood and it has not gone unnoticed by Irvine.
The North End boss told BBC Radio Lancashire: "He's done very well. He came back in very good condition and he's worked extremely hard in training.
"He's trying very hard to get himself a chance here. It's a huge year for him and he's got a chance."
He added: "I said, and I meant it, at the end of the season that everyone would start afresh so he's got that opportunity and it's important from his point of view that he takes that opportunity.
"If he doesn't then clearly it will not be good for him as far as being here in concerned. But, if he does there is a chance here for him.
"I'm not looking to move Jason Jarrett out. Obviously we're Preston, and if anybody comes on making enquiries about any of our players then we have to consider their enquiry."
