Raiders head coach Jack Del Rio gave Chiefs head man Andy Reid an all-time death stare Thursday night after Kansas City upended Oakland, 21-13.
TV cameras picked up Reid patting a pissed-off Del Rio on the back, but the two were reportedly cordial prior to that.
According to Chiefs blog Arrowhead Pride, Reid said he and Del Rio were cool.
"Not at all," Reid said when asked if there was any bad blood between the two. "Jack and I are actually good friends. I know people don't like to hear that because it's the Raiders. No, not at all. I know the picture, I patted him on the shoulder after we shook hands."
