IF Elfsborg have announced that coach Klas Ingesson has passed away at the age of 46.
The former Sweden international, who was capped 57 times by his country, had been fighting the effects of an incurable type of bone marrow cancer, multiple myeloma, since 2009.
"It is a very sad statement to make that Klas Ingesson this morning [Wednesday] passed away," read an Elfsborg statement.
"Our thoughts are foremost with his wife [Veronica] and children [Martin and David] who were with him at the end."
Ingesson, who enjoyed spells in Belgium, Netherlands, England, Italy and France during a peripatetic 15-year playing career, announced he was suffering from multiple myeloma in May 2009.
However, after undergoing a round of stem cell transplantation, he returned to the game the following year, taking charge of the Elfsborg Under-21s.
The former midfielder was forced to undergo a second round of treatment in January 2013 but he was nevertheless appointed co-manager of the senior squad in December.
Earlier this year, a wheelchair-bound Ingesson addressed the question of whether he should continue coaching in an open letter to his club's fans.
"The talk about my cancer has to end," he wrote. "Elfsborg and I have an agreement that I am manager for the first team.
"Physically and mentally I don't have a problem to do my job. I should be judged as anyone else to determine whether I am good enough for the job but then I should be judged on my competence, not my physical status.
"It is every person's right to be judged by who you are and what you do, not because you have an illness or a handicap."
Ingeson started his playing career in his native Sweden with Gothenberg before joining KV Mechelen in 1993. He enjoyed three years in Belgium before spending a season with PSV.
Two years at Sheffield Wednesday followed before a successful two-year stay in Bari earned him a move to Bologna in 1998.
Ingesson, who was a part of the Sweden side that finish third at the 1994 World Cup, left the Dall'Ara for Olympique de Marseille two years later but returned to Italy in 2001 to join Lecce, his final professional club.
