Dantonio's rolling contract, which stipulates that one year is added to his deal on an annual basis, extends through the 2024 season.
According to reporters at Friday's board meeting in East Lansing, Mich., the trustees did not discuss the contract at any length before approving the extension.
The 61-year-old Dantonio has denied accusations that he mishandled sexual assault claims against players on his team in the past. According to an ESPN "Outside the Lines" report, a minimum of 16 football players were accused of sexual assault or violence against women since Dantonio became coach.
Dantonio has been the Spartans coach since 2007, with a 100-45 mark in 11 seasons. Michigan State finished with a 10-3 record in 2017.

The school announced several staff changes, the most noteworthy being the promotions of Ben Albert and Matt Guerrieri to co-defensive coordinators.

--The University of Mississippi has filed an appeal of the NCAA committee on infractions' decision to ban the football program from postseason play in 2018, limit unofficial recruiting visits and cite the school for lack of institutional control in a case involving 21 violations.
The NCAA announced the sanctions in December after a lengthy investigation, saying the lack of institutional control went back decades, and charged that Rebel Rags, an Oxford-based retail store, provided free merchandise to recruits and family members.
Among the cases cited were incidents dating from 1986 and 1994.
The Ole Miss appeal reads in part: "This Committee should vacate and reverse the penalties and factual findings because the COI abused its discretion, departed from precedent, committed procedural errors, and reached factual conclusions inconsistent with the evidence."
--New Mexico head coach Bob Davie will begin his 30-day suspension Saturday.

Lobos athletic director Eddie Nunez announced in a statement that defensive coordinator Kevin Cosgrove will serve as interim head coach during Davie's suspension, which will run through March 18.
