Iowa State at Kansas State (2:30 p.m. Saturday, Fox Sports 1): This is a must win for Kansas State (3-4, 1-3 Big 12) if the Wildcats want to play in a bowl game this season, a long way down from last year’s run to a share of the conference title. Kansas State can get back to .500 for the season and would have to get two more wins this year with four games left. Barring a historic run to end the season, Iowa State (1-6, 0-4) will miss out on bowl season. But the Cyclones could still play spoiler.No. 18 Oklahoma State at No. 15 Texas Tech (6 p.m. Saturday, KDFW/Ch. 4): Texas Tech (7-1, 4-1 Big 12) is coming off a disappointing 38-30 loss last week at Oklahoma, a sloppy game that was delayed more than an hour by rain. The good news: There is a zero percent chance of rain in the Lubbock forecast for Saturday. Oklahoma State (6-1, 3-1) has won three straight since dropping its first conference game on the road at West Virginia. Both teams need a win to stay in the conference title picture, and both boast strong offensive attacks. This could be a high-scoring game, and the added Big 12 implications will add drama.
