Oklahoma lost to Iowa State, 54-75, Saturday in Ames and lost started Elijah Harkless to a season-ending undisclosed injury.

Iowa State was red hot. They shot 67.3% — the highest field goal percentage by a Big 12 school in three seasons. At one point, Iowa State made 18-of-21 shots.

It was the worst conference loss for OU this year.

“Really struggled guarding the dribbler early on. We switch a lot, and that’s really the No. 1 area where we missed Elijah. We felt it right away,” OU coach Porter Moser said. “Normally Jalen Hill, Jordan Goldwire and Elijah are three really good guys at guarding the ball. And when we switch a lot, it doesn’t really matter. Then you take one less out of there and you make a sub, you have three or four guys who aren’t good at guarding the dribble at one time.”
