Southern California extended the contracts of both its offensive and defensive coordinators, the school announced.
Terms and lengths of the extensions were not announced for either offensive coordinator Tee Martin or defensive coordinator Clancy Pendergast.
"To have two of the best coordinators in the industry back for their third consecutive seasons is a critical piece for our team's growth and our opportunity for success next season," Trojans head coach Clay Helton said in a statement.
Martin, 39, had been linked to a few high-profile coaching vacancies this offseason, including at his alma mater, Tennessee. He has been on the USC staff since 2012 and served as offensive coordinator the past two seasons.
USC ranked 13th nationally in total offense (484.1 yards per game) during the 2017 season under Martin's watch.
Pendergast, 50, has served as defensive coordinator the past two seasons. He also spent the 2013 season in that same capacity for the Trojans.
USC's defense limited seven opponents to season-low point totals in 2017 under Pendergast, who also has served as a defensive coordinator for six seasons in the NFL with the Kansas City Chiefs and Arizona Cardinals.
"Clancy and Tee are a huge reason why, in our first two seasons, we have won a Rose Bowl and Pac-12 Championship," said Helton. "Having both back will help us to our goal of having national championship-caliber seasons."
