The IFL have revamped the line-up for their Dec. 29 World Grand Prix card, allowing for a new 155-pound title clash and the introduction of the 145-lb. division into the organization.

Today, the IFL formally announced the full and revised line-up for their card at the Mohegan Sun in Uncasville, Conn., which will now feature a rematch between undefeated lightweight prospect Chris Horodecki (Pictures) and Shad Lierley (Pictures) for the IFL 155-pound title. The two met in June, where Horodecki took a unanimous decision in a fight of the year candidate. Horodecki's originally scheduled opponent, Waggney Fabiano, who submitted John Gunderson (Pictures) in the lightweight semifinals this month, will move down to featherweight to face off with undefeated LC Davis (Pictures) to crown the IFL's inaugural 145-pound champion and welcome the division into the promotion.

The other three IFL title bouts remain as scheduled. Antoine Jaoude (Pictures) and Roy Nelson (Pictures) will square off to crown the IFL's first heavyweight champion, each coming off of wins inside the distance over Shane Ott (Pictures) and Bryan Vetell (Pictures) respectively. Undefeated in his IFL tenure having stopped all five opponents including Brent Beauparlant (Pictures) in the semifinals, Benji Radach (Pictures) will take on Matt Horwich (Pictures), who quickly submitted semifinal foe Brian Foster (Pictures), for the 185-pound IFL crown. For the welterweight crown, Delson Heleno (Pictures), who submitted Gideon Ray (Pictures) in under two minutes in the semifinals, will take on Jay Hieron (Pictures), who is coming off a three round shutout of Donnie Liles (Pictures).

In the non-championship preliminaries, hard-hitting Miletich product Rory Markham (Pictures) will return to action against Renzo Gracie (Pictures) pupil Dan Miller (Pictures), IFL newcomers Marcelo Salazar will rematch Englishman Alex Cook who will be a part of Ian Freeman (Pictures)'s British-based IFL camp in 2008, and Elias Rivera will take on Tim Kennedy (Pictures).
