USC’s Su’a Cravens to undergo tests after injuring his knee

USC’s 44-17 victory over Washington State on Saturday came with a cost as Trojans linebacker Su’a Cravens suffered a knee injury.

USC officials said the sophomore was initially diagnosed with a sprain, but that he would undergo tests when the Trojans returned to Los Angeles.

Cravens was injured with 1 minute 33 seconds left in the second quarter when Washington State scored on a nine-yard touchdown pass. Cravens fell to the turf away from the play. He was assisted off the field and to the locker room, and was walking with crutches after the game.

Cravens said he had felt pain a few plays before.

“I just turned,” he said, “and it was hurting bad.”

Cravens made four tackles, including one for a loss, and broke up two passes.

Agholor enjoys big plays

Nelson Agholor caught eight passes for a career-best 220 yards and a touchdown and also returned a punt 65 yards for a touchdown.

Agholor established a USC career record with his fourth punt return for a touchdown.

Agholor also scored on a punt return this season against Arizona State. Last season, he scored twice on returns against California.

Agholor was wide open on an 87-yard touchdown pass play, the longest of his and quarterback Cody Kessler’s careers.

“I saw Cody throw it and I thought, ‘Please don’t overthrow him,’” said Coach Steve Sarkisian. “But it’s hard to overthrow No. 15. He has an innate ability to just kick into one more gear to go catch the football.”

Allen joins Allen

Tailback Javorius Allen rushed for 114 yards in 19 carries.

It was the sixth consecutive game that Allen rushed for more than 100 yards. He became the first USC player to achieve the feat since Marcus Allen did it in 11 consecutive games during his Heisman Trophy-winning season in 1981.

“Marcus Allen, that’s a great running back and he did amazing things,” Javorius Allen said. “To have my name associated with his is an honor.”

Javorius Allen has rushed for 1,124 yards and eight touchdowns. He has rushed for more than 100 yards in all but one game, the Trojans’ loss at Boston College.

Halliday injured

Washington State quarterback Connor Halliday suffered a broken right leg midway through the first quarter when he was hit by USC defensive tackle Leonard Williams while delivering a completed pass.

“I grabbed him and spun with him, and his legs were still under him,” Williams said. “But his body was going that way. I kind of landed on his ankle and actually I felt it pop.”

Halliday, who leads major college football in passing yards and touchdown passes, was carted from the field.

Williams said the play “was haunting me” because he had met Halliday at Pac-12 media day and enjoyed getting to know him. Williams said he planned to call Halliday on Saturday night.

Kessler and linebacker Hayes Pullard went onto the field to offer encouragement as medical staff attended to Halliday.

Kessler said he had spent time with Halliday at a football camp this summer and during media day.

“I just told him, ‘I love you, brother. Keep your head up. You’re going to bounce back from this, come back strong and get ready for the next level,’” said Kessler, who added that he also intended to contact Halliday.

Farmer steps up

Junior receiver George Farmer, sidelined the previous two games because of a hamstring injury, caught three passes for 61 yards.

Farmer had receptions of 20 and 24 yards on the first two plays of the game.

“It felt great,” he said. “I knew it was going to come. I just try to be prepared for it and be ready when my number is called.”

Pullard picks one off

Pullard intercepted a pass early in the first quarter to help set up USC’s second touchdown.

It was Pullard’s first interception this season, the third of his career.

Safety Leon McQuay III intercepted a pass to end the first half. It was McQuay’s second interception of the season, the third of his career.
