An NCAA investigation involving the football program at Nebraska is reportedly underway.

Longtime college football reporter Brett McMurphy, now with The Action Network, reported Wednesday morning that the Huskers program and head coach Scott Frost are being investigated for “improper use of analysts and consultants during practices and games.”

These allegations reportedly date back to last year and NCAA interviews, including with Frost, have already taken place:

The school, sources said, has “significant video footage” confirming the practice violations took place in the presence of Frost and other assistants.

Frost has obtained legal counsel, and the NCAA has interviewed Frost, multiple current and former staff members, administration and football players regarding the allegations, sources said. The allegations date back 12 months.

NCAA rules allow for just 10 full-time, on-field assistant coaches that can have direct contact with players. Graduate assistants also may instruct players both on the field and in the film room. Analysts and consultants can work with coaches, but cannot directly contact players.

Additionally, McMurphy is reporting that Nebraska conducted strength workouts at “an undisclosed off-campus location to avoid detection” during the COVID-19 pandemic, but it’s unclear whether that is part of the NCAA’s investigation. Organized team activities were banned by the NCAA during the pandemic.
