NFL referee Ed Hochuli found himself at the center of another controversy on Sunday after calling back an interception that was returned for a touchdown by the Panthers on Sunday. Two weeks ago Hochuli mistakenly ruled a fumble an incomplete pass that helped Denver rally to beat San Diego. This time Hochuli flagged Julius Peppers for roughing the passer, wiping out Matt Ryan's interception that was returned by Carolina's Richard Marshall for a touchdown. Hochuli ruled that Peppers made a helmet-to-helmet hit, but replays showed that Peppers hit Ryan with his shoulder first as Atlanta's quarterback released the ball. "I threw my shoulder into him, but I guess my helmet [hit his]," Pepper said.
