Weidman could end his career in a loss to Silva

Chris Weidman, former UFC middleweight champion, said he would have ended his career if he had lost to Bruno Silva in a recent fight.

"I still think I have a lot of potential. There have been a lot of challenges, but I can fight. It's too much fun and I think I'm built for it. I've thought about retiring a lot of times. If I had lost, if I hadn't had my hand raised, this fight could have been my last. If I realized in the octagon that I didn't have it in me anymore, I might have taken the gloves off. But that didn't happen, I got the victory, so I'm still here."
