The American Athletic Conference is going to have to look outside of the Mountain West Conference to add new teams.
Yahoo Sports' Pete Thamel reported Friday that Air Force and Colorado State have elected to stay in the MWC. The AAC was pursuing both schools.
The decision by Air Force and Colorado State came a day after Thamel reported that Boise State and San Diego State had decided to stay in the MWC for the time being.
Sources: Air Force and Colorado State will also be staying in the Mountain West.
