The inquest heard that CCTV showed Alex leaving a pub around 1am after a day of drinking with friends.
He was thought to have gone to another pub before stumbling home at 2.40 a.m.
The inquest heard how Alex’s post-mortem revealed he had a small subarachnoid haemorrhage, which occurs when a head injury causes bleeding in the space that surrounds the brain.
The 31-year-old also had an eye socket fracture.
A neurosurgeon said that while the haemorrhage could not be ruled out as the cause of Alex’s death, it was a possibility.
The death of the 31-year-old was ruled an accident by Assistant Coroner Sian Jones.
Toxicology tests revealed that he was intoxicated at the time of his death and that he had recently used cocaine.
She told the room: “I am satisfied he had been drinking and had taken some cocaine but neither of those were likely to be the direct cause of his death.
“However the alcohol did affect his mobility and stability and it’s likely to have caused or contributed to his fall because it would have increased the risk of him having a fall.
After the inquest Alex’s sister Vanessa told LancsLive: “He was loved by so many people.
“In Blackburn everyone knew him and I was known as Alex’s sister even though I’m older.”
Alex’s mum added: “He was over the moon about his new job. He’d found out earlier in the week and I can still see his face after he got the news; he was buzzing all week.”
