COLORADO SPRINGS, Colo. — Tanith Belbin and Ben Agosto won't win a record sixth ice dance title this year, withdrawing from this month's U.S. Figure Skating Championships because of his back injury.

The injury forced the Olympic silver medalists out of the Grand Prix final last month. While it's improving, Agosto said in a statement today that he hasn't been able to train at the level needed for nationals.

The couple does intend to compete at the world championships in March. Results there determine how many entries countries get for next year's Vancouver Olympics.
