Oklahoma star Rodney Anderson out for season with knee injury

NORMAN, Okla. --  Oklahoma Sooners junior running back Rodney Anderson will miss the rest of the season with a knee injury. It is a huge blow to the fifth-ranked Sooners' College Football Playoff chances.

The team announced the injury Sunday.

Anderson suffered the injury on the final play of the first quarter Saturday against UCLA. After being tackled by a pair of Bruins, Anderson came up clutching his right knee.

This is Anderson's third season-ending injury at Oklahoma. He was lost for the year in 2015 after going down with a broken leg two games into the season. The following spring, he suffered a fractured vertebra in his neck and was out for the season again.

Anderson came back to win the starting job midway through the season. Over his past seven games, he led the FBS in yards from scrimmage, culminating with 201 rushing yards and two touchdowns in the CFP loss to Georgia in the Rose Bowl.

Anderson was a preseason All-Big 12 section. He rushed for 100 yards and two touchdowns on only five carries in the opener two weeks ago against Florida Atlantic.

"It's unfortunate," said Kyler Murray, who, with Anderson out Saturday, became the first quarterback in four years to lead the Sooners in rushing. "We've just got to keep going."

In place of Anderson, the Sooners will turn to sophomore Trey Sermon to shoulder the rushing load. As a true freshman, Sermon ran for 744 yards and five touchdowns. He also caught a key touchdown from Baker Mayfield in the second half of Oklahoma's win at Ohio State. Sermon has 82 yards and a touchdown through two games this season.

Alongside Sermon, the Sooners will be leaning more on senior Marcelias Sutton and true freshman T.J. Pledger.

"We've got other good players in there," Riley said Saturday. "Honestly, play-calling-wise and design, it's not going to change a whole lot. We've got confidence in the guys we have there. They all have dynamic skill sets.

"That's part of the deal at that position. It's a physical position ... and we've worked hard to build depth there."
