SOUTH BEND, Ind. — Notre Dame is facing the possibility of losing three starters before the football season has even begun after another embarrassing hit for a university that prides itself on high academic standards.

The university on Friday barred KeiVarae Russell, the team’s best cornerback, leading returning receiver DaVaris Daniels, defensive end Ishaq Williams, and backup linebacker Kendall Moore from practice and games while it investigates “suspected academic dishonesty.”

The Rev. John Jenkins, Notre Dame’s president, said the school is looking into allegations the players had course work done for them.

The news comes a season after quarterback Everett Golson was suspended for the 2013 season for academic impropriety.

The Irish finished 9-4 behind Tommy Rees last season, but coming off an appearance in the BCS title game in 2012 it was a step back.
