Week two of March Madness begins, with four games played tonight across two networks. Both CBS and TBS are presenting doubleheaders (and will repeat the trick tomorrow night, completing the roster of Sweet 16 competitors.) CBS coverage, live from Cleveland, starts things off at 7 p.m. ET, with the first of two games from the Midwest bracket: No. 3 seed Notre Dame against No. 7 seed Wichita State, the lowest-ranked of tonight’s seeds to hit the court. On TBS, live from Los Angeles, the next game of the night is at 7:45 p.m. ET, with West No. 1 seed Wisconsin facing No. 4 seed North Carolina. Another No. 1 seed, the much-favored Kentucky, faces fellow Midwest team West Virginia (seeded No. 5) at 9:45 p.m. ET on CBS, and TBS provides coverage of the night’s final game: At 10:17 p.m. ET, No. 3 Arizona facing No. 6 Xavier in the West.
