Grant (6-3, 225, 4.45) becomes the 20th member of an OSU recruiting class that could end up with one more signee if Louisville (Ky.) Central defensive lineman Corey Peters picks the Buckeyes on Wednesday.
He is ranked as the nation's fourth-best junior college prospect by SuperPrep magazine. The Scout.com database lists Grant as a five-star player.
"After looking everything over and looking at Ohio State and Oregon, I chose Ohio State as the place where I will spend my next two years," Grant said.
"In the Big Ten, the linebackers can show their flexibility. Some of the teams pass the ball and some of them run the ball. I think I will be able to stand out more in the Big Ten. There will be a lot of stuff on the air about who will replace A.J. Hawk. I wanted to be a part of that."
A short time ago, we spoke with Grant for some additional comments.
"It is great to be a Buckeye," he said. "It felt right ever since my visit.
"Why Ohio State? Thats easy. It's linebacker university. I think I can play there and get the kind of exposure I need to get to the next level. It is the best place for me to be."
Grant plans on coming in for spring practice and will be competing at the SLB spot.
"I will there at the end of March," Grant said. "I will wear No. 9 or No. 4. I will be playing the Sam linebacker over the tight end. That is where I played in college."
Grant, a native or Norcross, Ga., played two seasons at CCSF and was ticketed to enroll at Florida this spring. But an admissions snafu there led him to re-open his college choice. He took visits to Ohio State and Oregon before settling on OSU. He will enroll at OSU for spring quarter and participate in spring drills.
He would have a chance to compete for one of the three open linebacker spots at Ohio State.
As a senior at Norcross, he had 35 rushes for 450 yards and six touchdowns. He originally signed to play college ball at Murray State, but ended up at CCSF instead.
As a freshman at CC of San Francisco, he had 90 tackles, six sacks, six blocked punts, four forced fumbles, and one fumble recovery. On offense, he had one rush on a fake punt for 65 yards. Grant was named first team all-conference on defense.
As a sophomore, he was the California JUCO defensive player of the year. He made 85 tackles, including six sacks. He also intercepted six passes and blocked six punts.
"I think the thing that makes me better is my speed," Grant said. "I think my speed and agility are pretty good. I know how to get hands off of me. I still have a lot of things to work on and I will get to work on that."
OSU previously took two players from CCSF in defensive lineman Paul Breed and linebacker James Cotton.
Grant is the first junior college signee in Jim Tressel's six years as the OSU coach.
