John Plattenburg, a defensive back from Houston, has signed a national letter of intent with USC, the school announced.
Plattenburg, 5-foot-11 and 180 pounds, played at Lamar High. He previously played at Corona Centennial High before moving to Texas.
USC Coach Steve Sarkisian had said that defensive backs were a priority in the 2014 class.
"He has a very high football IQ," Sarkisian said on the USC website. "He gets the game which allows him to make a lot of plays by anticipating what is coming."
Keith Heyward, USC's secondary coach, said on the website that Plattenburg was "very, very strong and kind of built up already. He looks like he's playing in college right now."
Plattenburg is the second defensive back to sign with the Trojans. USC announced that Lamont Simmons also had signed.
