[ESPN.com] Chiefs head coach Todd Haley said it was too early to know if quarterback Matt Cassel will miss a second straight start this weekend because of an injury to his left knee. But he is hopeful of making a decision earlier than Sunday, when the decision was made just hours before the season-opener at Baltimore.

If Cassel remains out, Brodie Croyle would make a second start, this one against Oakland, after earning generally high marks in the 38-24 loss to the Ravens.

“Matt is doing everything he can to be ready,” Haley said. “I would hope I would know a little sooner this week, although right now I can’t give a definitive answer. But the player’s doing everything he can to be ready, which generally helps speed the healing process.”
