"After a long thought process and strategic evaluation of the pros and cons of this decision with my close family and friends, I've decided to stay at Ohio State," Laurinaitis said in a statement issued by the school.

Laurinaitis, a 6-foot-3, 244-pounder from Hamel, Minn., won the 2007 Butkus Award as the nation's top linebacker and the 2006 Nagurski Award as the top defensive player in college football.

The Big Ten defensive player of the year this past season, he set a BCS championship game record with 18 tackles against LSU in the Buckeyes' 38-24 loss, their second consecutive national title game loss.

Laurinaitis, the son of WWE professional wrestler Animal from the Legion of Doom, led the Buckeyes with 121 tackles for the season.

Most NFL draft projections have pegged Laurinaitis as a high first-round draft pick. During Ohio State's preparations for the game with LSU he had batted away questions about what he would do next season.

"I know I can still improve as a player, and I know there is still much more to me and for the Buckeyes to accomplish," he said. "I want stay a Buckeye for another season. You only get to do this once, so I want to take full advantage. There are a lot of things that money can't buy, and some of those things are the experiences of a senior season."

Coach Jim Tressel disclosed in December that he had urged 13 juniors to file the paperwork with the NFL to receive scouting evaluations to determine what round the players might be taken in this spring's draft.
