A slew of fight updates have been rattled off for the UFC Fight Night 20 event we announced late this week.

Stars Josh Koscheck and Chris Leben have been tapped for the Fairfax, VA show as well as up-and-comers such as TUF 8 winner Efrain Escudero.

The exciting talent we can look forward to doesn’t stop there, though. 170 lbs.’ers Rick Story and Nick Lentz look to once again impress in separate matches. Both Welterweights competed in truly exciting bouts on the recent UFC 103 under card. In fact, Story won both Fight of the Night and Submission of the Night honors with his win over Brian Foster. Lentz secure a solid decision victory over the tough Brazilian Rafael Oliveira.

The unofficial but expected UFC Fight Night 20 card is shaping up as follows:

Josh Koscheck vs. Mike Pierce
Chris Leben vs. Jay Silva
Rick Story vs. Jesse Lennox
Efrain Escudero vs. Nick Lentz
Tom Lawlor vs. Aaron Simpson
Mike “Joker” Guymon vs. Rory MacDonald
