Sports Jeopardy! shut down production in 2016 after recording just 12 of 52 episodes of season three. The "official" word from Sony is that SJ! is on hiatus (on their ticket website, the show promised updates on future tapings in both March and April. Now it says it has no information on tape dates for this year).
NBCSN started airing episodes previously seen on Crackle during last year's Summer Olympics, but I believed the network stopped airing them in May.
AFAIK, there has been no announcement of a cancellation (and I believe J! was still signing up people for a future SJ! online test as late as this past spring), but the odds don't seem great of a return.
