ULM vs. Texas: Longhorns blow out Warhawks 51-3 in Arch Manning’s 1st start Behind a smothering defense and Arch Manning's first career start at quarterback, the Longhorns clobbered Louisiana-Monroe 51-3 Saturday to end the nonconference schedule with a 4-0 record. Texas allowed 111 yards of total offense and Manning threw for 258 yards in the win. Mississippi State lost its SEC opener Saturday to the Florida Gators 45-28 and starting quarterback Blake Shapen suffered a season-ending shoulder injury. Shapen transferred from Baylor in the offseason and gave the Bulldogs some stability at quarterback after Will Rogers left for Washington. Freshman Michael Van Buren Jr. filled in for Shapen against the Gators and is expected to be the starter against Texas. The Bulldogs are 1-3 with consecutive losses to Arizona State, Toledo and Florida. They won their season opener 56-7 over Eastern Kentucky.
