Colorado QB Tyler Hansen leaves game against No. 12 Oklahoma State in second quarter

Colorado QB Hansen leaves game vs. No. 12 OSU

STILLWATER, Okla. — Colorado quarterback Tyler Hansen has left the Buffaloes’ game at No. 12 Oklahoma State with a right thumb injury.

Hansen was sacked three times in the first quarter and had a 4-yard rush on the series before he walked off the field and toward the locker room midway through the second quarter.

A team spokesman says X-rays on Hansen’s thumb came back clear but his return is questionable. Hansen broke the thumb during Colorado’s spring game when he slammed it into another player’s helmet.

Cody Hawkins, the Buffaloes’ starter at the beginning of the season, replaced Hansen on Colorado’s next drive. He threw a 5-yard touchdown pass to Riar Geer to give Colorado a 14-10 halftime lead.
