Despite Nebraska's desire to find a replacement contest for this weekend on short notice, the Big Ten didn't approve the request.
"We believe the flexibility to play non-conference games could have been beneficial not only for Nebraska, but other Big Ten teams who may be in a similar position as the season progresses," Moos and Green said in a statement. "The ability for all Big Ten members to play a non-conference game if needed could provide another data point for possible College Football Playoff and bowl consideration.
"Ultimately, the Big Ten Conference did not approve our request, and we respect their decision. We are excited to move forward with preparations for the rest of the season, beginning with next week's game at Northwestern."
The Cornhuskers reportedly tried to schedule a game against the University of Tennessee at Chattanooga before the conference denied the bid.
Wisconsin paused all team-related activities Wednesday due to an elevated number of COVID-19 cases within the program. Starting quarterback Graham Mertz and head coach Paul Chryst are among those who recently tested positive.
"Throughout the COVID-19 pandemic, the safety and well-being of our Nebraska student-athletes has been our top priority, and we know Wisconsin is operating with the same guiding principle," Moos and Green said. "We wish all of those impacted in the Wisconsin program a quick and full recovery from the virus."
