The league said positive coronavirus cases and subsequent contact tracing forced the game to be put off. Many Navy athletes are under quarantine, and the Midshipmen have temporarily halted all football activities.
"Protocols and guidelines are very comprehensive both at the Naval Academy and within the American Athletic Conference," Navy athletic director Chet Gladchuk said. "An administrative decision has been made that clearly reflects the safety and welfare of all involved with both institutions."
Neither team shares a common open date for the rest of the season, but the American said it will consider "a number of options" for rescheduling.
"We knew that this season would be different in the face of the pandemic, and unfortunately has forced another weekend without football for our team," Tulsa athletic director Rick Dickson said in a statement. "I'm disappointed for our football student-athletes and coaches who continue to work and practice diligently, but it reinforces the challenge facing all programs."
