According to Tito Ortiz's official twitter, which he stated today that Coleman "sissied out", he still plans to "kick someone's ass November 21st!" It's on Sherdog and a couple other sites as well so apparently Coleman pulled out of the fight and Ortiz is now without an opponent.
Well theres still plenty of time for a replacement which lets face it will probablly be better then Coleman.
Coleman pulled out due to injury. Don't know why he is calling him a sissy, Tito of all people should know what getting injured is like. Hopefully the replacement is better then Coleman. We all know the UFC made that fight so Tito could get a easy win.
Most the top LHW guys are in scheduled fights so I doubt it will be anyone good. Here is Coleman's manager response to Tito. http://www.fightersonlymagazine.co.uk/news/viewarticle.php?id=3197
