Nebraska has not released information this year about Pelini's contract in response to requests from ESPN.com and other media outlets. Athletic director Shawn Eichorst has not commented on the matter. He declined again this week in a face-to-face inquiry from the Omaha World-Herald.

The extension became a topic of interest as Pelini's contract, previously scheduled to expire on Feb. 28, 2018, dipped under four years. The coach received a $100,000 raise last week to $3.075 million, per the terms of his original five-year deal, signed in 2011. He was awarded one-year extensions by former athletic director Tom Osborne after the 2011 and 2012 seasons.

Pelini, 58-24 at Nebraska, is scheduled to address the media on Saturday after the Huskers' first of 15 spring practices.
