Warren has taken three trips, to Arizona, Cal and Michigan and is set to visit USC this month and Ohio State in January. He also plans to unofficially visit UCLA sometime in January.
"I am going to USC on December 16th," said Warren. "Coach (DeWayne) Walker (UCLA) will be here on Friday to talk with me and it depends on what I hear, but I might take a trip there instead of Ohio State. Coach Beckman from Ohio State is supposed to come in for an in-home visit with me sometime this week."
Warren was set to visit Oregon, but dropped the Ducks, enabling USC to get a visit, which will be his fourth trip.
The Trojans have long been on Warren, recruiting him the longest and hardest throughout the last year, and Warren said that loyalty was one of the reasons why he's visiting there.
Should Warren not visit Ohio State, he said UCLA would end up getting his fifth visit. If he does trip to Ohio State, Warren said he will definitely be taking an unofficial trip to Westwood.
Last weekend, Warren got to see two of his final schools face off against each other when he took in the USC-UCLA game at the Rose Bowl.
"I saw some things I liked from both teams defense, but Coach Walker called a real good game and their defense knocked USC off track," said Warren. "I went into the locker room after the game and it was crazy in there, all this excitement. But I'm not basing my decision just on that game."
Following the visit to USC, Warren will lay low from recruiting, enjoy the holidays and then depart for San Antonio at the end of the month for the U.S. Army All-American Game.
"I'm real hyped for that opportunity, to go up against the best players in the country," said Warren.
Warren and his Jackrabbit teammates had their season come to a close with a heartbreaking 23-22 loss to Orange (Calif.) Lutheran on Friday night in the CIF Division I semifinals.
