The NCAA placed Air Force's football program on probation for two years Thursday and issued other penalties for recruiting violations committed during COVID-19 dead periods.

The NCAA said the Air Force Academy and four individuals involved in the alleged violations reached an agreement with enforcement staff about penalties. A fifth unnamed individual is fighting the allegations, and his case will be resolved through an infractions hearing.

The Action Network, citing sources, reported in May that the Falcons were being investigated for hosting high school prospects on campus during dead periods in 2020 and providing them with improper benefits.

Former Falcons defensive line coach Bill Sheridan was one of the coaches involved in the investigation, according to the Action Network. Sheridan, who coached the defensive line at Air Force, resigned as Wisconsin's inside linebackers coach on May 13.
