Former welterweight champion  Leon Edwards lost his second fight in a row last Saturday in the UFC London main event at the O2 Arena. “Rocky” was largely dominated by  Sean Brady and former multiple-time title challenger  Colby Covington believes it’s time for Edwards to retire.  “I kind of thought that after I fought Leon, you know, he just the motivation wasn’t there anymore. I mean, I could tell in the fight, like, I broke my foot immediately and he did nothing. He didn’t try and come after me.
