The results of an internal investigation into academic fraud has reportedly cost Notre Dame four key players as it readies for the 2014 season.

FoxSports reported Friday that "four starters have been dismissed" from the team and school over the alleged fraud, uncovered during the summer investigation.

247Sports' Blue and Gold Illustrated reported Friday that cornerback KeiVarae Russell, defensive end Ishaq Williams, linebacker Kendall Moore and wide receiver DaVaris Daniels were not with the team at its Friday practice. Notre Dame declined comment on those players' absences.

FoxSports reported the same four players were those dismissed after the investigation. Yahoo! Sports reported the academic investigation also included regular Notre Dame students as well as football players.

If reports prove true, it's not immediately clear if the four players would be permitted to apply for re-enrollment. Everett Golson was named the team's starting quarterback after missing the 2013 season through academic suspension and applying for re-enrollment this past spring.
