Forward Alex Morgan is not the starting lineup for the United States' Women's World Cup opener against Australia.

The speedy 25-year-old, who has 51 goals in 84 international appearances, has a bone bruise in her left knee and hasn't played in a match since Portland's National Women's Soccer League opener on April 11.

Morgan is listed as a substitute for the No. 2 U.S. against the 10th-ranked Matildas in Monday night's lineups. Abby Wambach and Sydney Leroux were down to head the attack.

The U.S. is seeking its third World Cup title but first since 1999 after losing the 2011 final to Japan on penalty kicks.
