Óscar Tabárez will remain Uruguay coach for four more years, until the end of the 2022 World Cup in Qatar.
The Uruguayan Football Association announced the contract extension on Friday without elaborating. Tabárez signed under the auspices of an intervention commission from FIFA, which is managing the association to February, when a disputed election is hoped to be resolved.
It will be his fifth World Cup cycle with Uruguay, the fourth in a row. His best results are fourth place at the 2010 World Cup in South Africa, and winning the 2011 Copa América in Argentina.
He will keep assistants Celso Otero, Mario Rebollo, and José Herrera, who have worked with him since 2006.
Tabárez, who suffers from a nerve disorder that forces him to use crutches to walk, has been in charge of Uruguay since 2006. He was also the coach from 1988 to 1990 prior to that.
The 71-year-old has led Uruguay for 185 games, a record for any international coach. He has also taken the country to four World Cups, another "record for a coach with a single national team," said the association.
Uruguay reached the semi-finals of the 2010 World Cup in South Africa and the quarter-finals in Russia earlier this year.
Tabárez's spell in charge has coincided with a golden generation of Uruguayan players, notably strikers Luis Suárez of Barcelona and Paris Saint-Germain's Edinson Cavani, as well as the now-retired Diego Forlan before that.
The announcement comes at the end of a trying few weeks for the Uruguayan Football Association following the sudden resignation of Wilmar Valdéz as president in July, one day before he was due to stand for re-election, due to some compromising audio recordings.
That plunged the federation into chaos and led football's world governing body, FIFA to take over its running a month ago.
The continued stability of Tabárez's leadership of the team presents is widely seen as a welcome boon for Uruguayan football.
His next matches in charge will be October friendlies against Japan and South Korea.
Tabárez previously coached AC Milan and Cagliari in Italy while in South America he led giants Boca Juniors to the Argentine Apertura title in 1992 and Uruguayans Peñarol to their last Copa Libertadores success in 1987.
