UNC released their schedule today. They will host the Bison on November 15th as a preliminary part of the Phil Knight Nike event that hadn't been announced before. I assume that is also what the game with Arkansas will be - which means it will be in November (or very early December) as well.
UNC's
release describes the Bucknell visit as "an early-round game."
Arkansas hosts Samford on Friday Nov 10, and Bucknell is said to be hosting Siena on Nov 21. If the rumored Arkansas game is also "early round" and the Maryland rumors are true, that could mean the Bison are lined up for an intense road swing:
Nov 12 or 13?: at Arkansas
Nov 15: at North Carolina
Nov 18: at Maryland
