As reported on Fighters.com, Jim Hettes was injured in training and out of his UFC 159 bout with Steve Siler. UFC scrambled to find a last minute replacement and they have now confirmed that Strikeforce import Kurt Holobaugh will step in to face Siller. Holobaugh was 9-0 going into the final Strikeforce card in January, but lost via decision to Strikeforce number one contender Pat Healy. He looks to rebound in his UFC debut.
