As has been stated before, big offensive tackle Demetrius Knox was formerly of Springfield, Ohio.
A Texas commit, Knox is visiting family in Ohio the weekend of April 19-21.
Knox has told me that during that trip he will give Ohio State a visit. OSU was believed to be Texas' strongest competition before he committed to the Longhorns.
Update: Demetrius Knox is actually on OSU campus today (3/23) with teammate and fellow Texas commit Daniel Gresham. He's pictured above posing with Braxton Miller at the Woody Hayes Athletic Center.
