Goalkeeper Kasey Keller, who would likely have started against Trinidad & Tobago on Sunday because rival Brad Friedel is not on the roster, wonÆt be joining the USA on its trip to Port of Spain. According to U.S. Soccer, Keller aggravated an injury to his left ankle in training with the national team this week. No additions will be made to the now 20-man roster for the Nov. 11 match (ABC, live, 2 pm ET). ôItÆs only a minor problem, but itÆs something that needs looking after,ö said Keller. ôIÆm obviously disappointed that I wonÆt be able to play against Trinidad, but in the end the best thing to do is take care of it now so I can resume playing as quickly as possible.ö Keller was scheduled to return on Thursday to England, where heÆs a reserve keeper for Tottenham Hotspurs. Either the Chicago FireÆs Zach Thornton or the Miami FusionÆs Nick Rimando will start against T&T.
