Light heavyweights Matt Hamill and Thiago Silva are expected to square off in October at UFC Fight Night 29 on the new FOX Sports 1 network.
The bout would take place October 9 from Brazil.
Hamill (10-4) returned last year after a brief retirement to defeat Roger Hollett. Silva (15-3) has spent time on the sidelines due to failed drug tests and injuries, but topped Rafael Cavalcante recently.
The bout was first reported by Knockout Radio.
