Ohio State will host Ryan Kalkbrenner, a four-star center prospect for the class of 2020, on an unofficial visit Sunday.

A 6-foot-11, 210-pound center, Kalkbrenner is preparing for his senior season at St. Louis (Missouri) Trinity Catholic. He earned a scholarship offer from the Buckeyes in mid-June to add to a list of suitors that also includes Illinois, Purdue, Cincinnati, Xavier, Creighton and Kansas State, among others.

In the 247Sports.com composite database, Kalkbrenner is listed as the No. 3 recruit from Missouri, the No. 13 center in the nation and overall No. 77 prospect.

Ohio State has one available scholarship for the class of 2020 and has been looking to add some size to its roster for the class.
