No specific date or location has been confirmed by UFC officials, however March 3rd, 2012 is the most common report.
The news comes one week after Kampmann's stirring victory over rising contender Rick Story at UFC 139. Prior to the win, the 29-year-old suffered through a controversial two-fight slump, dropping a razor-thin split decision to Jake Shields at UFC 121 and a contentious unanimous decision to Diego Sanchez in March.
Likewise, Alves recently righted his own sinking ship with a dominating TKO win against heralded prospect Papy Abedi at UFC 138. Prior to the bout, the Brazilian's record was marred by decision losses to Georges St. Pierre, Jon Fitch, and Story in three of his previous four contests.
