The 145-pound contest is expected to serve as the co-main event of the card, which is headlined by an interim bantamweight title fight between reigning champ Renan Barao and No. 1 contender Michael McDonald.
Swanson (18-5) has emerged as a potential title challenger over the last year after back-to-back-to-back knockout wins against George Roop, Ross Pearson and most recently, Charles Oliveira. The 29-year-old was pegged as an inconsistent fighter not long ago but his skills appear to be coming together at the right time.
Of Swanson's 18 professional wins, seven are by knockout, seven are by submission and the remaining four are via decision.
Siver (21-8) is taking no time to rest after his extremely lopsided victory over Nam Phan at UFC on FOX 5 last weekend. The German fighter has looked unstoppable since dropping to 145-pounds from the lightweight division as seen in his two clear-cut wins over Diego Nunes and Phan.
The 33-year-old is known as one of the most dynamic strikers on the UFC roster, even though he hasn't finished a fight by (T)KO since November 2009.
One man will continue to climb the featherweight ladder while the other will have to go back to the drawing board. Don't blink when these two step in the cage.
