The NFL plans to give referee Ed Hochuli lower grades after he erred on a call late in Sunday's San Diego-Denver game, according to Associated Press. "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." The play occurred with the Broncos at the Chargers' one-yard line in the final minute. Denver's Jay Cutler dropped back to pass, and the ball slipped out of his hands, bounced off the grass and into the arms of San Diego linebacker Tim Dobbins. Hochuli ruled it an incomplete pass. Replay ruled it a fumble, but it was spotted at the 10-yard line, where the ball hit the ground, and given to Denver because the rules did not permit possession to be awarded to San Diego because the whistle had blown.
