During College Football season, Wheel of Fortune's Saturday edition (mostly reruns) often gets pre-empted on WABC and other ABC affiliates due to the games rarely ending on time. A local newscast is scheduled for 7:00 after the game (which bumps Saturday Jeopardy! to either early Saturday or Sunday morning, or in rarer cases, Sunday afternoon), with WOF afterwards at 7:30.
If the game runs over less than 10 minutes or so, they'll simply truncate the news and still end it at 7:30. If the overrun is 10-20 minutes, it runs half an hour and WOF gets joined in progress around the third round. If the game runs over at least 20 minutes, the news will run straight to 8:00 with no WOF.
In November 2016, WOF scheduled a new episode on the Saturday of Election Day week because of a notable episode being initially scheduled for Election Day itself. They aired the week's episodes in a M-W-Th-F-S format, with no new episode on Tuesday. Unfortunately, the Saturday episode suffered overrun fate and was pre-empted completely in NYC and other markets that scheduled it for 7:30.
This also happened with the Black Friday NFL game last November. The game was scheduled to end at 7:00 with no news padding afterwards, so the 7:00 hour was listed as Jeopardy! and Wheel as usual on WABC. The game ended up not signing off until around 7:30, and then after several commercials, Wheel was joined in progress about 5 minutes in. NYC did not get that day's Jeopardy! episode at all, and they did not delay it to Saturday like some stations sometimes do. Other stations like WPVI Philadelphia did put news padding at 7:00 and bumped J! overnight, and J! ended up getting the last laugh in the end because the "7:00" news ended up running until 8:00 and Wheel wasn't seen at all.
