Manny Pacquiao: 'Two to three years' left in boxing

One of boxing's biggest stars is close to the end of his career, but there's still good time left, according to Manny Pacquiao, who said in Singapore that he has "two to three years" left in the ring, which is pretty consistent with what he's been saying for the last few years.

Pacquiao (54-5-2, 38 KO) will face Brandon Rios on November 23 in Macao, China, headlining again on HBO pay-per-view. He went 0-2 in 2012 and is in desperate need of a win.

"Brandon Ríos is a good boxer, a tough opponent and I believe we can give a good fight. Especially his style and my style it is very good to fight each other, we can create a lot of action in the ring. I'm not really sure (how many fights left). As long as I can still fight, I can fight. In my mind right now, maybe I can still fight maybe two to three years from now.

"I tell you frankly, honestly in myself I can still fight and I feel strong. If there is something wrong in my body or something wrong in my boxing skill I have to think about that and think about retirement. But since I lost the last fight, I still feel strong and I can still fight."

Manny will turn 35 in December, and has shown some signs of physical decline the last few years, which has been natural given his advancing age and the fact that he's had a long, hard, busy career that has seen him fight from 112 to 154 (well, 150) pounds, winning titles at 112, 122, 126, 130, 135, 140, 147, and 154 (well, 150).

How long do you think Manny has left? And if he loses to Rios in November, do you think that will signal him to turn off the lights on his boxing career?
