SOUTH BEND, Ind. — Dr. Phil McGraw says Ronaiah Tuiasosopo, who masterminded the dead girlfriend hoax involving Manti Te’o, told him the Notre Dame linebacker was not involved in the scheme and that he ended up falling ‘‘deeply, romantically’’ in love with the football player.

McGraw spoke on the ‘‘Today’’ show Wednesday, previewing an interview he did with Tuiasosopo, a 22-year-old California man who created the fictional woman Te’o knew as Lennay Kekua. Tuiasosopo’s interview with McGraw will air in two parts on the ‘‘Dr. Phil Show’’ starting Thursday.
