It turns out the move to take out starter Matt Cassel wasn't made to spark the Chiefs' offense. Coach Todd Haley told reporters after the game Cassel was injured, prompting the switch to Palko with the game within reach with less than two minutes remaining. "Matt was unable to go," Haley said. "He was beat up there at the end. I will let you know later in the week." Cassel left the stadium wearing a cast on his right hand, according to The Kansas City Star. Cassel wouldn't provide any details during his postgame news conference, protecting the nature of his injury. He said he wanted to go back in, but was told by the team's medical staff he could not return. "I don't want to get into specifics, but yes, I couldn't go back into the game," Cassel said.
