Honor&Glory on buckeyeplanet.com says that Colerain LB Cobrani Mixon has been offered. I regularly peruse the recruiting board on BP; it's extremely thorough and, if you can get past the juvenile name-calling, an excellent resource for recruits that are also considering OSU. Generally, that's a lot. H&G seems like a very legit poster and claims to be a former Colerain player.
Mixon suffered an ACL tear last year which must have been partial because he played on it a few months after the injury. So he's one tough SOB. I'd look for a commitment from him in the near future if H&G is indeed correct.
