Texas A&M quarterback Haynes King is undergoing surgery for a fractured tibia. King underwent a successful surgery on Sunday, for the injury which occurred during the Aggie's 10-7 win over Colorado. The redshirt freshman is expected to miss at least a month, but head coach Jimbo Fisher declined to give an exact timetable for his return. Zach Calzada will take over at QB for A&M as they prepare to face New Mexico at home on Saturday.
