Warren committed to FSU defensive coordinator Mickey Andrews during a home visit Monday night. Warren said he was recruited as a safety.
"He's very excited," Madison County Coach Frankie Carroll told TheTerritory.
Warren, a highly-rated safety known for his aggressiveness and tackling skills, had listed FSU and Florida as his co-leaders.
Still, other notables such as Clemson are were high on Warren's list.
In fact, an Iowa State coach spent nearly four hours at Madison County High School earlier last week visiting with Warren and coaches.
Warren is scheduled to visit FSU Jan. 30. He said he has canceled his remaining visits. Warren also still needs to acamdically qualify.
Warren said he also has had an opportunity to watch the replay of the Cowboys' state-championship defeat (27-0) to Hollywood Chaminade. Warren chipped in 81 rushing yards on five carries in that game and was credited with nine tackles.
"We just had too many mistakes and too many penalties (20)," Warren said. "But we had a great season, and we are having a lot of fun (tonight)."
Warren represents FSU's eighth commitment.
