Receiver Javon Walker will make his Raiders' debut on Sunday against the Chiefs, according to Associated Press. He still has some pain in his injured hamstring, but he will tough it out against Kansas City. Coach Lane Kiffin said he has not decided whether to start Walker or Ashley Lelie at split end. "He just can't really push off it right now," Kiffin said Friday. "He came out yesterday and tried a little bit, he thought it was getting better, just not a lot of strength in it right now."
