Nigerian media reports this morning said Keshi passed on suddenly.
TheCable, Nigeria's independent online newspaper, confirmed his death from a member of his family as well as one of his close associates.
He was 54 year's old and is survived by four children and his mother.
The former international football player and coach had lost his wife of 33 years, Kate, last year after a prolonged battle with cancer.
Keshi, nicknamed the 'Big Boss' for his leadership skills, is the fifth member of the all-conquering 1994 team to pass away, following Uche Okafor, Thompson Oliha, Rashidi Yekini and Wilfred Agbonavbare.
He rose to national prominence when he debuted for the Super Eagles in 1981, at age 20.
The late central defender withdrew from the national team in 1994.
He had 64 caps and scored nine goals.
