TV Insider:
Jeopardy! Season 40 kicks off on Monday, September 11, but like the rest of Hollywood is affected by the ongoing writers (and actors) strikes, meaning there will be quite a few changes. So, will everyone be watching as usual?
The game show returns with Ken Jennings as its host — he closed out Season 39 after Mayim Bialik stepped away out of solidarity with the writers, before the actors went on strike — but with no new contestants and questions written before the strikes.
Instead, starting on September 11 is a Second Chance Tournament with players who appeared in Season 37. (The first week’s starting matchups are as follows: operations manager Jill Tucker, scriptwriter Gabriel Ostler, and accountant Derek Allen; assistant editor Cody Lawrence, magnetics engineer David Maybury, and baker Susan Schulman; and hardware engineer Hari Parameswaran, writer Donna Vorreyer, and aerospace engineer Matt Wierman. The winners will then face off.)
The winners of that tournament will then take on champions from Season 38 in Champions Wild Card.
