The Defense Department has suspended intercollegiate athletic competitions at the nation's service academies due to the government shutdown.
The U.S. Naval Academy subsequently announced that it will cancel games as appropriate.
A soccer game Tuesday night against Howard was the first game to be cancelled. Navy said it's not known whether the game will be made up or not.
As for Saturday's scheduled football game featuring Navy and Air Force in Annapolis, Navy said it would make an announcement before noon on Thursday.
But it's looking increasingly likely that the contest - which is set for a national broadcast on CBS at 11:30 a.m. Eastern - won't take place.
After Navy's announcement, the Air Force Academy's athletic department announced that it has suspended travel for all of its intercollegiate athletic events, including the football game. The Air Force Times reported that the travel ban is in place for all service academies.
Army has yet to make any formal announcement. Its football team is scheduled to play at Boston College on Saturday, with a 1:00 p.m. kickoff and a national broadcast on ESPN3.com.
A Pentagon spokesman, Army Col. Steve Warren, told the Associated Press that the suspension is being reviewed by Pentagon lawyers to determine whether funds used for these activities are congressionally appropriated funds.
