LOS ANGELES (AP) — Lincoln Riley arrived at Southern California on Monday with a determination to restore the Trojans to their former place atop the college football world.

Riley agreed to leave Oklahoma after five seasons for a new challenge on the West Coast, roughly 24 hours before he arrived in Los Angeles to start his new job.

He addressed his new players before receiving his official welcome at the Coliseum in what he called "a surreal moment."

Riley said he was happy in Norman, but the opportunity of a new challenge on the West Coast was too fascinating to resist.

Riley confirmed that several OU coaches, including defensive coordinator Alex Grinch, receivers coach Dennis Simmons, director of operations Clarke Stroud, and strength coach Bennie Wylie would join him in Southern California, the Associated Press reported.

As OU picked up the pieces, they named Bob Stoops as interim head football coach.

Also, on Monday, former Heisman Trophy front runner Spencer Rattler announced that he was leaving Oklahoma and entering the transfer portal.

NORMAN, Okla. —

An Oklahoma man was reunited with the doctors who saved his life after going into cardiac arrest.

Christopher Fennell was having dinner while visiting his son in Norman, Oklahoma. And as they were leaving a restaurant, Fennell fell to the ground and went into cardiac arrest, which led to a brain seizure.

"I was basically dead, and they brought me back," he said.

His son is now a junior at the University of Oklahoma and is studying pre-med. He knew exactly what to do to keep his father alive until paramedics arrived.

"The quick action of my son to call 911 and then hand the phone to my wife, who was in shock and started CPR was, I mean, I wouldn’t be here without that," Fennell said.

Fennell was taken to the hospital, where he stayed in the ICU for 10 days.

"Out-of-hospital cardiac arrest does not have a very good prognosis overall," Dr. Archana Gautam said.

Fennell was later sent to rehab, where he was able to get additional treatment and fully recover.

"To see someone physically recover and cognitively recover after a cardiac arrest is rare," said Dr. Lane Tinsley.

Fennell said without the quick medical attention from his son, paramedics and the doctors — he wouldn’t have fully recovered.

"All of these things God put in place, put breadcrumbs down on the ground to get me here, for the great people here to continue my recovery, put me on the road to recovery and get me back in the position I am in today," he said. "I am a walking miracle, but this is not a story about me. This is a story about how God works in the world today."
