The path to what some fans hope will be a national championship season is now set in stone as Ohio State football finalized its 2013 schedule Friday.

Fifteen days after Vanderbilt canceled its trip to Columbus for next year, the Buckeyes added San Diego State for a Sept. 7 contest against the Aztecs in Ohio Stadium.

“San Diego State has a fine football program and we are happy to be able to add them to our schedule,” OSU athletic director Gene Smith said in a released statement.

“We have had an excellent relationship with SDSU over the years with three exciting, competitive games since 2001.”

The 2013 game will be the fourth time the two teams have met since 2001.

The Buckeyes, which hold a 3-0 advantage in the series, have outscored the Aztecs, 70-31 over the course of contests in 2001, 2003 and 2005.

SDSU, which finds itself currently a member of the Mountain West Conference, will move to the Big East next season a long with fellow MWC member, Boise State.

Other non-conference opponents for the 2012 season include Buffalo, Florida A&M and California.

OSU continues its 2012 campaign against Illinois Saturday at 3:30 p.m. at Ohio Stadium.
