QB Cate starts in place of Robinson for No. 12 Oklahoma State

STILLWATER, Okla. -- Junior Alex Cate made his first career start at quarterback for No. 12 Oklahoma State on Thursday against Colorado in place of injured starter Zac Robinson.

Cate had thrown only five passes in his career at Oklahoma State before being called on to replace Robinson, the school's career record-holder in total offense, passing and touchdown passes.

Robinson left last week's victory against Texas Tech after a big collision with safety Jamar Wall with less than 2 minutes remaining.

Cowboys coach Mike Gundy had indicated he expected Robinson to start against the Buffaloes, although the team's medical staff was still performing tests on him through the week.
