The Chiefs announced the signing Wednesday. They open a three-day rookie minicamp Saturday.
Murray was considered a first-round talent a year ago, but he had this past season cut short by a torn ligament in his knee. The former Georgia star is also considered small for the position, standing 6-foot and weighing about 200 pounds.
Still, the Chiefs believe Murray could push second-year pro Tyler Bray for the No. 3 job, and perhaps even supplant Chase Daniel as the backup to starter Alex Smith.
