It's repeat night, so you can catch up on some of the premieres you may have missed earlier this week.
CBS has "CSI" with Laurence Fishburne at 8pm and "The Good Wife" at 9pm. If you missed "The Good Wife," you should tune in.
NBC airs "Law & Order" again at 8pm, followed by "Mercy" at 9pm, and "Law & Order: SVU" at 10pm.
ABC has college football -- Iowa at Penn State.
Also, "Making His Band," the P-Diddy reality show airs at 9pm on MTV. Wilson NC's Jamareo Artis is still in the competition.
And if you're hooked on "The Locator," as we are, tonight Troy Dunn will facilitate a reunion between a woman and the daughter she gave up for adoption. That's on at 9pm on We (channel 61 on cable).
The biggest news of the night is the premiere of "Saturday Night Live," with summer It-Girl Megan Fox and musical guest U2. A little SNL summer controversy involved Lorne Michaels cutting solid performers Micheala Watkins and Casey Wilson from the show. The very funny Watkins was known for her portrayal of Arianna Huffington and Hoda from "The Today Show." Michaels replaced Watkins and Wilson with two women from The Upright Citizens Brigade.
