Cregg's offensive line received the Joe Moore Award — given to the nation's top offensive line — in 2019 when the Tigers won the national championship.
"You also admitted to knowing such contact was impermissible when you engaged in the conduct," says a letter from LSU coach Ed Orgeron to Cregg dated June 2 that is included in the lawsuit. "This knowing violation of NCAA rules constitutes cause."
If Cregg's firing with cause holds up, he would not receive the remainder of his $700,000 salary package owed to him for the remaining months of the last year of his contract in 2021.
LSU has refused since June to release such correspondence to the Lafayette Advertiser, which has made public records requests for the information.
Cregg contends in the lawsuit that LSU fired him without regard to any NCAA findings on his conduct with a recruit.
