10. Sean Salmon (21 losses)
Salmon’s MMA career had started with so much promise. The wrestler from Ohio got the call from the UFC in 2007, when his record was an impressive 9W-1L.
In his first UFC fight he was KO’ed in the 2nd round by a Rashad Evans head kick and had to be carried out on a stretcher. He would lose his next fight to Alan Belcher before getting cut from the UFC.
Around 2009 the sport seemed to pass Salmon by, and in 2010 he embarked on an epic 12 fight losing streak in which he was finished in all 12 fights. Not wanting to go for 13 straight losses, Salmon finally decided to hang em up with a career record of 18W-21L
