New York ? Ed Hochuli’s acknowledgement that he erred on a call late in Sunday’s San Diego-Denver game will mean lower grades for one of the NFL’s highest profile referees.

“Officials are held accountable for their calls. They are graded on every play of every game,” NFL spokesman Greg Aiello said Monday. “Ed has been an outstanding official for many years, but he will be marked down for this call. Under our evaluation system, an official’s grades impact his status for potentially working the playoffs and ultimately whether or not he is retained.”
