The midfielder confirmed that his broken metatarsal bone will keep him out for around three months.
He is reported to have said: "The pitch was pretty poor, I seemed to buckle my foot and I knew straight away because I felt something pop," he said.
"I went to a specialist and we've ruled out it being a stress fracture. We think it is a straight break."
He added: "I went straight over to the bench after we had scored and I said to Mike Banks I think I have broken something in my foot.
"The boss said to come off but I wanted to carry on. Everyone knows my situation and I just wanted to impress.
"Maybe I've made it a bit worse but I just wanted to stay on. It was probably stupid. It was only five minutes after coming on and I didn't want to come off.
"If I can be back in late February, early March I will be really happy."
