The National Football League will review Peyton Manning's record-breaking feat during the Denver Broncos' 34-14 victory over the Oakland Raiders on Sunday.

According to ESPN NFL writer Jeff Legwold, the league will have a second look on Manning's record-breaking night after he shattered both the passing touchdown and yardage record.

"Peyton Manning's stat line from the Denver Broncos' 34-14 win Sunday over the Oakland Raiders was 25-of-28 passing for 266 yards and four touchdowns. The four TD passes gave him 55 for the season, extending his record total to five more than Tom Brady's former mark. The yardage total gave Manning 5,477 -- one more than Drew Brees' 2011 record," ESPN stated.

The report said the league's record-keepers are reviewing the validity of Manning's seven-yard pass to Eric Decker with under a minute left in the first quarter of that match.

"Manning set the mark on the last play from scrimmage for the Broncos before halftime, a 5-yard touchdown pass to Demaryius Thomas. He did not play in the second half. In one camera angle, the pass to Decker looks like a lateral, which would make it a running play. Another angle, from above, shows Decker receiving the ball at the Broncos' 48-yard line, with Manning slightly deeper than that."

If the record stands, Manning will hold the record as the most prolific quarterback in a single season. If it doesn't, Manning's output is still the highest in his legendary football career.
