Johnson said in the Yorkshire Evening Post: "It's frustrating for me to be told I won't be playing again this season after being out for so long with injury.
"It's a nightmare, but there's not a lot I can do. It's out of my hands what's gone on in the contract. I was looking forward to this weekend's game. I know the season is nearly at an end, but we had three games left and I was looking forward to playing in all of them. But it's not be so we'll have to see what happens in the summer.
"I want to get a good pre-season behind me and see what happens then. Pre-season is my target now. I want to stay here and do well for this club."
