Peyton Manning broke new ground in the NFL at the weekend as he surpassed Drew Brees' single-season yardage record during the Denver Broncos' defeat of Oakland Raiders. The iconic quarter-back could, however, be stripped of this achievement.
Manning, who had already broken Tom Brady's record for the most regular season touchdown passes, entered into the game with the Raiders in the knowledge he needed 266 yards to move ahead of Brees' 2011 total of 5476.
The 37-year-old achieved the exact yardage required in the first-half as he completed 25 of 28 passes, including four TDs, and Manning was withdrawn after the second quarter with the record in the bag.
However, Doug Farrar of Sports Illustrated claims Manning could quickly lose this record because of a contentious pass to Eric Decker during the first quarter of the 34-14 Broncos win.
Manning was credited with a seven-yard completion on a first-and-five but footage appears to show that the ball was thrown backwards, which means it should be classed as a lateral.
The Elias Sports Bureau could now review the tape of the game and change the classification of this instance from passing yards to running yards, meaning that Manning would fall six yards behind Brees.
Manning, though, will be more concerned with taking the Broncos to the Superbowl, and they remain the overwhelming favourites after scoring 606 points during the regular season.
