The United States Taekwondo Team faces its final chance to qualify four weight divisions for the 2012 Olympic Games in London when competition begins at the Pan American Olympic Qualification Tournament this weekend in Queretaro, Mexico. A top-three finish is needed to qualify each weight class.

Attempting to qualify the female -57kg division on Saturday will be 2008 Olympic bronze medalist Diana Lopez (Sugar Land, Texas), while 2011 Pan Am Games bronze medalist Terrence Jennings (Alexandria, Va.) will look to qualify the male -68kg class.

On Sunday, three-time Olympic medalist and five-time world champion Steven Lopez (Sugar Land, Texas) will attempt to secure the male -80kg division, and 2011 Pan Am Games silver medalist Paige McPherson (Sturgis, S.D.) will aim to lock up the female -67kg class.

Should any of the athletes qualify their weight divisions this weekend, they will then fight off against a top U.S. challenger in March for the individual spot on the 2012 U.S. Olympic Team. The challenger will be determined from the pool of original Olympic Trials qualifiers who will compete at an Olympic Trials Fight-Off Jan. 12-13 in Colorado Springs.

Here are the brackets for this weekend's competition:

Female -49kg
