Via The Detroit News:

In the filing, La Keshia Neal, mother of five-star recruit Daelin Hayes, alleged Dantonio, Blackwell and two other MSU coaches were in her home on or around Dec. 7, 2015. Days later, Hayes committed to Notre Dame. 

The filing came hours after MSU officials acknowledged for the first time the university is investigating allegations of misconduct and is in contact with the NCAA and Big Ten conference. 

Lawyers for Dantonio, in a court filing on his behalf later Tuesday, said he didn’t recall the visit nor authorize Blackwell, who by NCAA regulation was prohibited from off-campus visits, to be there.
