The Hilltoppers landed their 17th commitment on Tuesday evening when Mary Persons (Ga.) offensive lineman Caleb Etheridge announced his decision on Twitter.
The 6-foot-3, 285-pound prospect received an offer from the Hilltoppers back in the spring and has visited campus on multiple occasions.
The Georgia product chose Western Kentucky over the likes of Middle Tennessee, Marshall, and others.
Etheridge joins Deshon "D.J." Washington, Woodford Lankford, and Patrick Nuss as offensive line commitments in WKU's 2017 class.
