(CNN/Bleacher Report)-- Peyton Manning's single-season passing yards record may wind up being the shortest-lived record of all time.
According to SI.com's Doug Farrar, the NFL is in the process of reviewing a seven-yard completion from Manning to Eric Decker in the first quarter of the Denver Broncos' Week 17 blowout win over the Oakland Raiders that, if overturned, would result in Manning finishing the 2013 regular season with 5,470 yards, six shy of Drew Brees' previous all-time record set in 2011.
Manning completed 25 of 28 passes for 266 yards and four touchdowns in the 34-14 win despite sitting the entire second half.
As The Denver Post's Mike Klis points out via Twitter, an overturn of Week 17's ruling would sting for Manning and Broncos fans as the future Hall of Fame passer could have easily broken the mark in the third quarter:
From one angle, the quick pass to Decker looks like a lateral, which would make it a running play. However, other angles are inconclusive.
This certainly isn't the first time Manning has found himself in the midst of record-breaking controversy. After he broke Tom Brady's single-season passing touchdown record on Dec. 22 against the Houston Texans, the NFL announced that the record-tying 50th touchdown pass to Decker should not have counted since the receiver bobbled the ball before running out of the back of the end zone.
Broncos head coach John Fox had the following response when asked whether Manning would have played at all during the second half of Week 17's rout if the all-time single-season passing yards record was still on the line, per Farrar:
That’s hard to say. What was very positive was I thought we played one of our better halves of football that put us in a position where we could do different things. Number one, all those things are great—those individual accomplishments, team accomplishments—but not at the risk of putting a player at risk. So I don’t know if I’ve answered your question, I’m just kind of telling you what would go through our minds in that situation.
Regardless of the NFL's final ruling, Manning and the 13-3 Broncos will head into the postseason as the AFC's No. 1 seed for the second straight year. Denver is now just two wins away from earning a trip to Super Bowl XLVIII.
While Manning would love to secure another individual record, he'd likely trade it all for a second Lombardi Trophy.
