Line: Oklahoma State by 13.
WHAT'S AT STAKE
Oklahoma State need to win to keep pace with Texas Tech, Texas and Baylor, all of whom enter the weekend unbeaten in the Big 12. The Cyclones have to win five of their last six games to be bowl eligible for the fourth time under coach Paul Rhoads.
Iowa State's defensive line vs. Oklahoma State's offensive line. The Cowboys haven't announced whether J.W Walsh or Clint Chelf will start at quarterback, but neither of them will be very effective if the line can't protect them. Iowa State hasn't been great at getting at the quarterback though, with just 10 sacks through six games.
PLAYERS TO WATCH
Oklahoma State. WR Josh Stewart. He had 265 yards in last week's win over TCU, including a 95-yard punt return for a score. Stewart's prowess as a returner could help spark Oklahoma State's offense, which struggled against the Horned Frogs.
Iowa State: QB Sam Richardson. He was pulled for the first time in last week's 71-7 loss to Baylor. Richardson will start against the Cowboys, but a rough showing could quickly land him back on the bench.
