No. 20 Louisiana-Lafayette (8-1, 6-1 Sun Belt) at Appalachian State (7-2, 5-1 Sun Belt), Friday, 8:30 p.m. EST (ESPN).

Line: Appalachian State by 3.

Series record: Appalachian State leads 8-0

WHAT’S AT STAKE?

Pride and perhaps a little revenge. Lafayette has already clinched a spot in the Sun Belt Conference championship game on Dec. 19 against Coastal Carolina, which knocked off two-time defending champion Appalachian State this year in the Eastern Division. The Ragin' Cajuns lost the previous two championship games to the Mountaineers, so this will be their chance at revenge in a series App State leads 8-0.
