Warnock said: "I've spoken to our medical staff and they've told me Djibril's suffered the same injury I had. It was my second break in a year. I had to have a steel rod put into my leg during the operation, so I know exactly what he's going through.
"The first thing you need to know in these situations is that the doctor thinks the operation has been a success and there are no complications.
"My girlfriend spoke to Djibril's girlfriend last night and they were all very happy with how the operation went.
"When I saw the pictures I felt sick. My leg came out at a similar angle. In my case, I was out between ten-and-a-half and 12 months, but you really don't think about playing again at this stage.
"A lot of it is a psychological process. When you get back to training, running and putting in a few tackles, that's when you know everything is going to be okay.
"You've just got to be as positive as you can be until then and refuse to let it beat you. I was determined to do whatever it needed to get back and play at the highest level and I'm sure Djibril will be the same.
"The fact I managed to come back has proved Djibril can also make a full recovery. If he looks at my situation, he'll know it's possible and I'll be around to give any advice if he needs it. It's just a very long process."
