Brazil Star Marta May Start World Cup on Bench Due to Injury

Brazil striker Marta may start the Women's World Cup on the bench due to a left knee injury.
Brazil coach Pia Sundhage is unsure how long Marta will be able to play in each match.
Sundhage emphasizes the importance of building a strong team, not just relying on one player.
Marta recently returned from surgery for a torn ACL and months away from the national team.
Brazil is in Group F with France, Jamaica, and Panama and will announce their final squad Tuesday.
