Pennington (15-8) has won five straight. The Colorado native is coming off a split decision win over Ketlen Vieira in January. Pennington, 35, has the second-most wins in division history (11) and is ESPN’s No. 1-ranked women’s bantamweight fighter.
Bueno Silva (10-2-1, 1 NC) is unbeaten in four straight fights. The Brazilian fighter stopped Holly Holm via submission in July, but the bout was overturned to a no contest and Bueno Silva was suspended 4½ months due to a failed drug test for a prescribed (but undisclosed) ADHD medication. Bueno Silva, 32, is tied with Ronda Rousey for most submissions in division history (3).
The Pennington-Bueno Silva fight was first reported by Brazilian outlet AG Fight.
