“I was having to get up a few times in the middle of the night to use the toilet and had a weak stream,” Knight added.
“So when I was getting a blood test for something unrelated, I spoke with the nurse about doing a PSA test.
“I probably would have put it off otherwise, but I’m glad that I didn’t.
“Ironically, it has spread to my hip, which I’ve had a few problems with down the years, but I have been told that it’s manageable.

Symptoms can include struggling to urinate or emptying your bladder, a weak flow and needing to urinate more than usual.

As a teenager, Knight kept a clean sheet on his debut against Rotherham in Division Three in 1978 and he went on to represent the club in all four divisions. He was awarded an MBE following his retirement.
Knight’s final appearance for the club came on 3 January 2000, in a 2-1 Division One defeat at Norwich, making him the only Blues player to have played across four decades.
