Oklahoma State sailed through its first three games. Practices, not so much.
During the week, the Cowboys lost starting guard Larry Williams to a season-ending ankle injury, leaving them without two regulars up front as tackle Zach Crabtree missed Saturday's game with a toe injury.
OSU had previously lost key reserve linebacker Kevin Henry to a season-ending knee injury suffered in practice, the same week linebacker Kenneth Edison-McGruder was hurt during a workout.
For a Cowboys team ranked No. 6 and sensing a special season, adversity has arrived, beyond Saturday's 44-31 loss to TCU.
