WBFF in Baltimore apparently needed to air a Washington Football preseason game last night, so they booted the Field of Dreams game to the MyNetworkTV affiliate WUTB. As a result, whereas Jeopardy probably would've been preempted, it ended up airing as scheduled since the football game started later than the baseball game.
In the past, I know I've seen Washington Football preseason games on WNUV, the CW affiliate (Ravens' preseason games are usually covered by the NBC affiliate, WBAL). I guess I'm surprised that, presumably due to something contractual, this preseason game took precedent over a special/sports event by FOX and that the FOX game didn't even go to the CW affiliate, but got bumped to MyNetworkTV.
