Tina George (Colorado Springs, Colo./New York AC), the No. 1 seed at 55 kg/121 lbs. in women's wrestling, has received an extension on her Championship Series for the U.S. World Team due to injury.    George notified USA Wrestling on Thursday of her injury, and will not participate in the World Team Trials in Ames, Iowa, June 18-19. Because she notified USA Wrestling by the deadline, she did not have to weigh-in for this event. George said she had both hand and knee injuries.    Replacing George as the No. 1 seed in the competition, and moving directly into Saturday's Championship Series at the weight class, will be 2005 U.S. Nationals runner-up Marcie Van Dusen (Colorado Springs, Colo./Sunkist Kids).     The winner of the Championship Series at this division does not earn a spot on the World Team, and will have to wrestle George in a best-of-three series at a date and location to be determined prior to the World Championships.    *****    2004 Olympic silver medalist Sara McMann (Iowa City, Iowa/Sunkist Kids) has entered the World Team Trials in Ames, Iowa at 63 kg/138.75 lbs., her first competition since winning her historic Olympic medal in Athens, Greece last summer.    McMann will be entered in the Challenge Tournament portion of the competition on Saturday, because she did not participate at the U.S. National Championships in Las Vegas, Nev. She qualifies for the competition as a past World and Olympic Team member. McMann received the No. 1 seed in the Challenge Tournament at this division.    The 2005 U.S. Nationals champion who is automatically in the Championship Series is Alaina Berube (Escanaba, Mich./New York AC). McMann defeated Berube in two straight matches in the final series of the 2004 U.S. Olympic Team Trials in Indianapolis, Ind. last May.    ****    2004 Olympic silver medalist Stephen Abas (Fresno, Calif./Sunkist Kids) did not enter the World Team Trials freestyle competition. He could not compete because of a medical condition.    One of the 2004 Olympians who has chosen to continue his career, Abas moved up from 55 kg/121 lbs., where he won his Olympic medal, up to 60 kg/132 lbs. this season. Abas competed at the 2005 U.S. Nationals in Las Vegas at 60 kg. Abas lost in the quarterfinals to eventual champion Michael Lightner (Norman, Okla./Sunkist Kids), then withdrew from the national tournament and did not place. Abas was qualified for the World Team Trials as a past World and Olympic team member.    Because Abas did not compete, he will not earn a national team ranking for the 2005-06 season. The World Team Trials is the event that sets the national team each year, with the top three placewinners in the event recognized as members of Team USA.    ****    2004 Olympic Trials finalist Jake Clark (Colorado Springs, Colo./U.S. Marine Corps) has basically been out of action for the past year due to military obligations. On Thursday, he showed up for the weigh-ins looking lean and ready to compete. He will wrestle at his usual weight of 84 kg/185 lbs.    Clark has wrestled in five events this year, winning medals at four, including two golds. Most recently, Clark placed first at the Armed Forces Championships at the end of March.    Clark, who has spent his time traveling back and forth between Okinawa, Japan and the U.S., is seeded first in Saturday's Challenge Tournament.    ****    The qualifying procedures for the World Team Trials event in freestyle wrestling includes allowing all 2005 NCAA Championships finalists into the Challenge Tournament portion of the tournament. This year, nine NCAA finalists will be competing against the nation's best Senior-level athletes in freestyle.    2005 NCAA champions entering the event are Zack Esposito of Oklahoma State at 66 kg/145.5 lbs., Chris Pendleton of Oklahoma State at 84 kg/185 lbs. and Steve Mocco of Oklahoma State at 120 kg/264.5 lbs.    2005 NCAA runner-ups entering the event are: Nate Gallick of Iowa State at 60 kg/132 lbs., Phillip Simpson of Army at 66 kg/145.5 lbs., Johny Hendricks of Oklahoma State at 74 kg/163 lbs., Ben Askren of Missouri at 84 kg/185 lbs., Sean Stender of Northern Iowa at 96 kg/211.5 lbs. and Cole Konrad of Minnesota at 120 kg/264.5 lbs.    Some of these NCAA finalists qualified for the event other ways. Both Gallick and Mocco placed second at the U.S. National Freestyle Championships in Las Vegas, Nev., which is a qualifying event. Askren and Stender also qualified by winning one of the USA Wrestling Senior Regional competitions held earlier this fall.     ****    2003 World bronze medalist Jenny Wong (Colorado Springs, Colo./Sunkist Kids) dropped a weight class down to the lowest division, 48 kg/105.5 lbs., in her quest to make the U.S. World Team. She received a No. 1 seed in the Challenge Tournament at the weight class.    Wong won her World medal at 51 kg/112.25 lbs., and placed third at the 2005 U.S. Nationals at that weight class. In 2004, in an attempt to make the U.S. Olympic team at one of the four Olympic weight divisions, Wong competed up at 55 kg/121 lbs. in the U.S. Olympic Team Trials.    2004 Olympic bronze medalist Patricia Miranda (New Haven, Conn./Sunkist Kids) has not competed since her medal performance at the Athens Olympic Games, leaving the 48 kg/105.5 lbs division up for grabs.     The 2005 U.S. Nationals champion is Sara Fulp-Allen (El Granada, Calif./Sunkist Kids), who has advanced to Sunday's Championship Series. Also entered in the tournament at this division is 2004 U.S. Olympic Team Trials runner-up Clarissa Chun (Colorado Springs, Colo./Gator WC), who did not compete at the U.S. Nationals due to injury. Chun received the No. 2 seed in the division at the Challenge Tournament.    ***    FILA, the international wrestling federation, announced new Greco-Roman rules for international wrestling two weeks ago, and these new procedures will be used at the World Team Trials.     These rules were used in the recent Asian Championships, and official notice of the rule adjustments was announced in early June. The new rules will be used at the World Championships in Budapest, Hungary, Sept. 26-Oct. 2.    Except for in training, none of the U.S. athletes in Greco-Roman have competed using these new rules. The rules provide for wrestling in the par terre position (on the mat) to occur after one minute of each period.
