The NCAA agreed Tuesday to settle a class-action head-injury lawsuit by creating a $70 million fund to diagnose thousands of current and former college athletes to determine if they suffered brain trauma playing football, hockey, soccer and other contact sports.

College sports' governing body also agreed to implement a single return-to-play policy spelling out how all teams must treat players who received head blows, according to a Tuesday filing in U.S. District Court in Chicago. Critics have accused the NCAA of giving too much discretion to hundreds of individual schools about when athletes can go back into games, putting them at risk.

Nate Craig, the No. 1 ranked wide receiver and No. 6 player overall in the ESPN Junior 300, has committed to Auburn.

Craig chose Auburn over USC, Alabama and Ohio State.

"I just thought Auburn was the best fit for me," Craig said. "I got to go up there this weekend and spend some time with coach [Dameyune] Craig and coach [Gus] Malzahn and that just sealed the deal for me. I was at Alabama for the whole week, but just building a relationship with the Auburn coaches and coach Craig was a big impact on my recruitment and did a great job. With coach Malzahn I got to spend some time with him and then I sat down with my mom and decided to make a decision."

The athletic pass-catcher who totaled 37 receptions for 502 yards and 12 receiving touchdowns as a sophomore, said Auburn fans can expect to get a hard working player when he gets on campus.

"I'm a hard working - humble guy," he said. "A guy that is going to make his teammates better and keep my head on straight on and off the field and it's going to be a fun time playing in front of the War Eagle fans."

Maty Mauk of Missouri has compared himself in style to Johnny Manziel.

"I feel like I have the ability to do similar things, and that's what people are expecting of me back in Columbia (Mo.)," Mauk said Wednesday at SEC Media Days.

Mauk threw 11 touchdowns and two interceptions while filling in for the injured James Franklin last season.

"The stuff he could do was unbelievable. People had never (seen) it. You're a freshman Heisman Trophy winner," Mauk said. "He could turn anything into a big play. That's what I liked about him, and that's why I watch him on film."

With injuries and constant double-teams, Jadeveon Clowney didn't have as productive of a season in 2013 as many were anticipating.

Clowney has said he never gave serious thought to sitting out ahead of the 2014 NFL Draft.

"Jadeveon didn't even have to play last year," Steve Spurrier said. "A lot of people advised him to sit out. He wanted to play."

Clowney underwent sports hernia surgery in June.

Jameis Winston served as a counselor at the Manning Passing Academy over the weekend and aspires to be a quarterback like a Manning.

"I'm an observer," Winston told reporters, "so I just observe the way (Peyton) does things. He's so detail-oriented. And how he carries himself -- I'm really trying to see how he carries himself because I want to be the guy 10, 15 years from now that's viewed like a Peyton Manning or an Eli or an Archie."

Winston has a national title ring and a Heisman Trophy.

Baylor is installing a statue of Robert Griffin III at McLane Stadium.

Midland, Texas native Tom White of Tom White Studios in Prescott Valley, Ariz., completed the 9.5-foot bronze sculpture of Baylor's only Heisman Trophy winner and it will be installed in the south end zone plaza of McLane Stadium the week of Baylor's season opener against SMU on Sunday, Aug. 31.

The official pose is being kept under wraps until the final unveiling.

Dorial Green-Beckham, who was dismissed by Missouri in April after several off-the-field incidents, was added to Oklahoma's roster Thursday after a morning visit with the Sooners.

One of college football's most explosive receivers, Green-Beckham had a breakout season for the Tigers in 2013 with 59 receptions for 883 yards and 12 touchdowns as a sophomore. He was one of the nation's top recruits in the Class of 2012, ranking No. 3 on the ESPN150.

"We are pleased to welcome Dorial to the University of Oklahoma, where he is excited to continue his education and resume his playing career," Sooners coach Bob Stoops said in a statement. "Dorial understands the privilege and responsibilities of representing the Oklahoma football program. He is a talented young man who is eager to get to work with the rest of our team in the classroom and on the field."
