FORT COLLINS, Colo. (AP) The field at the new on-campus football stadium at Colorado State will remain named after one of the winningest coaches in school history courtesy of a $20 million donation.

The university announced Friday that a donor who wanted to stay anonymous committed funds over the next 30 years to transfer the name ''Sonny Lubick Field'' from Hughes Stadium to the new multi-purpose stadium that's set to open for the 2017 season. The announcement was made as the Rams kicked off spring football.

Lubick, who led the Rams to nine bowl games, said in a news release he's ''thrilled that our connection to the university and the program will continue in this way.''
