AMES, IA – The No. 3 Horned Frogs (6-0, 3-0 Big 12 Conference) are struggling to keep up with Iowa State after a first half full of injuries, reviewed plays and an ejection Saturday night at Jack Trice Stadium.

TCU’s defense proved nearly nonexistent, allowing for more than 300 yards and three touchdowns against an unranked Iowa State (2-3, 1-1) team.

Both Josh Doctson and KaVontae Turpin were injured and sent to the locker room in the first quarter. Doctson returned to the sideline at the beginning of the second quarter and caught a reception later in the quarter.

In less than a quarter, quarterback Trevone Boykin had already connected with Doctson seven times for 129 yards and a touchdown. Boykin set a new record Saturday night, as he is now responsible for 100 career touchdowns.

Iowa State quarterbacks Sam Richardson, Joel Lanning and Holden Kramer combined for 237 yards. Allen Lazard led the Cyclone receiving corps with 141 yards, including one 74-yard catch.

The few saving graces for TCU’s defense were from defensive ends Josh Carraway and Mike Tuaua, who got a sack and a fumble recovery, respectively. Linebacker Travin Howard led the Frogs in tackles, totaling four unassisted and one assisted.

With eight minutes left in the half, safety Denzel Johnson was ejected for targeting.

While the Frogs didn’t have many time-consuming rushing plays, the Cyclones had the ball for five more minutes than TCU, which proved costly for the depleted Horned Frog defense.

TCU ended the half with a 23-yard field goal from Jaden Oberkrom after rushing attempts couldn’t make it the final two yards and a delay-of-game penalty pushed the Frogs back.
