30 For 30 on ESPN at 9:00pm ET. Tonight’s episode is “Chuck & Tito” focusing on the MMA moguls.

Arrow on The CW at 9:00pm ET. Eighth season premiere.

The Purge on USA at 9:00pm ET. Second season premiere.

Treadstone on USA 10:00pm ET. Series premiere. This is a new series set in the Jason Bourne world, set in the actual black ops program “Operation Treadstone” that was referenced frequently throughout the Bourne movies. Which might be interesting, in that the Bourne franchise seemed to be doing a really slow burn towards being actual sci-fi and I’ll be curious to see if the series leans a little harder into that. Especially since the film that made it most explicit was the Jeremy Renner Bourne movie which seems to have been mostly been disavowed.

Battle of the Fittest Couples on Paramount at 11:00pm ET. Series premiere. The first episode of this is called “Swolemates” just so you know what you’re getting into.
