8 p.m. on WTVD The Bachelor
Former NFL athlete Colton Underwood, this season’s Bachelor, is hoping the third time’s the charm as Season 23 of this matchmaking reality series gets under way. Underwood previously appeared as a contestant on Season 14 of “The Bachelorette,” but was sent home disappointed at the end. A subsequent recent summer appearance on “Bachelor in Paradise” likewise failed to produce a true love match. He starts his “Bachelor” season with a newfound clarity and determination. Guest stars in the premiere include Megan Mullally, Nick Offerman, Terry Crews and Billy Eichner.
