Ultimate Fighting Championship (UFC) will soon enshrine two more of its greatest stars in the Hall of Fame, coinciding with the historic 100th pay-per-view (PPV) event scheduled for July 11 weekend at the Mandalay Bay Events Center in Las Vegas, Nevada.

The dynamic duo was not revealed at this time; however, the announcement is expected to be made at the first-ever UFC Fan Expo on Friday, July 10, 2009 (unless, of course, the information is leaked sooner.)

Here’s a snip from UFCFanExpo.com:

"Join us on Friday, July 10, immediately following UFC President, Dana White's keynote address, as two worthy members of the UFC world will join the ranks of Dan Severn, Mark Coleman, Ken Shamrock, Randy Couture, and Royce Gracie when they are inducted into the UFC Hall of Fame. You won't want to miss this historical event happening right on the UFC Fan Expo show floor!"

Currently, there are five members of the UFC Hall of Fame: Mark Coleman, Randy Couture, Dan Severn, Ken Shamrock and Royce Gracie. Coleman was the most recent addition, celebrating his induction last year in front of a hometown crowd at UFC 82: "Pride of a Champion" in Columbus, Ohio.

Former middleweight champion and epic adventurer, Evan Tanner -- who succumbed to heat exhaustion and perished during a solo camping trip in a scorching California desert in September 2008 -- would be a logical posthumous choice. And former light heavyweight champion Chuck Liddell -- who has yet to personally announce his retirement despite Dana White’s best efforts -- would be another.

But, again, the identities of the next two future Hall of Famers remain a mystery … for now. Who do you think should get the nod?
