There is no towel to throw in MMA... or is there?

UFC3 was the last time a corner had to throw in the towel during a MMA fight. The referees since then have been given the knowledge and power to be able to stop a fight if they believe the fighter can't continue. And we haven't seen that old white towel again.... until now.  Check out this article on the Bellator 60 Fight that happened last friday: http://www.mmamania.com/2012/3/12/2863329/would-throwing-in-the-towel-have-saved-joe-warren-from-excessive#storyjump
