Donald Cerrone replaces Sam Stout
Stout is dealing with the unexpected passing of his longtime trainer and brother-in-law Shawn Tompkins earlier this month. UFC officials confirmed the switch to ESPN.com Monday.

Siver (19-7) also looks to strengthen his case for a run at the title. The German lightweight has won four straight and eight of his last nine.
He turned in a terrific performance at UFC 127 in February, scoring an upset win over George Sotiropoulos in Australia. In his last fight, Siver won a somewhat controversial decision over Matt Wiman at UFC 132.
