In the end, no disciplinary action will be taken against the Buffaloes.
With 3 minutes, 29 seconds to play in CU's 33-28 victory, freshman quarterback Adrian Martinez injured his right knee while being tackled by Buffs' linebacker Jacob Callier. Martinez's right leg was caught underneath him as he was then also hit by Nate Landman and Israel Antwine.
Although he didn't name specific players, Frost felt the play was egregious enough to turn it in to the Big Ten and Pac-12 for review.
"I was made aware that Scott Frost and Nebraska submitted a play for review with the Pac-12 Conference office," CU head coach Mike MacIntyre said in a statement released Monday night. "Our athletic department officials have had discussions with the conference office; no one has been suspended and we are moving forward."
During a press conference with Nebraska media on Monday, Frost was asked if he thought it was a dirty play.
"You never want to think anybody on a football field would intentionally try to hurt someone else, and nobody except someone that does that knows what the intentions were," Frost said. "I will tell you we have an angle that doesn't look very good. The angle I've seen that I don't think is out there doesn't look good at all."
Martinez missed the rest of the game, but Frost said Monday the injury doesn't appear to be serious, listing Martinez as day-to-day.
"He's a little sore, but doing a lot better today than I expected and I don't think it'll be very long," Frost said.
