Police have launched a murder investigation and two men from Lancashire have been arrested after the incident, which took place at Central Drive at 5.33pm on Saturday.
Officers were called to reports of people fighting, and upon arrival found 22-year-old Ryan David Harvey with a serious head injury.
He was taken to Royal Preston Hospital for treatment but Ryan never recovered and was pronounced dead on Tuesday morning.
In a tribute, Ryan’s family said: "A family has lost their little boy due to an incident that happened on Saturday in Blackpool.
"Our little Ryan was a bubbly lad who would do anything for anyone.
"Ryan was a lifelong Walsall FC fan who lived and breathed football.
"We are absolutely heartbroken and would appreciate some privacy at this time to grieve for our loss."
Friends and family have shared moving tributes online to the massive Walsall fan, and a GoFundMe page has raised more than £2,000 to help his family pay his funeral costs.
A post mortem concluded that the cause of Ryan’s death was blunt head trauma, with enquiries to establish exactly how Ryan came about his injuries are ongoing.
