News broke early Sunday morning that Denver Broncos quarterback - and University of Tennessee legend - Peyton Manning plans to retire from football.

10Sports took a moment to reflect on the impact Manning had on the game during his time here in Knoxville with a list of his Top Five moments.

No. 5

1997 Citrus Bowl vs. Northwestern:

In what many thought could be Peyton's last game as a Vol, he lit up Northwestern for 408 yards and two touchdowns. It was Peyton's first 400-yard game. Luckily for Vol fans, it wasn't his last in a Tennessee uniform.

No. 4

Peyton wins duel vs. Kentucky and Tim Couch:

Peyton's battle with Kentucky's Tim Couch was Manning's most prolific passing performance at Tennessee. His 523 yards stood as a school record until 2012. Manning threw 5 touchdowns and no interceptions in what SHOULD have solidified his Heisman Trophy chances.

No. 3

Peyton vs. Bama in '95:

The legend of Peyton Manning was born on this night in Birmingham. The Vols hadn't beat the Tide in 10 years. And it all started on play...number...one. A long strike to Joey Kent. Manning...a sophomore...threw for 301 yards, and the Vols won 41-14. He was 3-1 all-time against the Tide.

No. 2

Peyton returns for his senior season:

You can still hear the sigh of relief from Big Orange Nation. No one really knew what Manning would do. Not players, not family members...not even Coach Fulmer. But Peyton iced his status as a Vols legend by coming back for one more year.

No. 1

Peyton helps Vols win 1997 SEC Championship:

Peyton will be remembered for losing the Heisman Trophy...but it was a team award that he should be celebrated for most. Manning led a double-digit comeback in the Georgia Dome to beat Auburn for Tennessee's first SEC title since 1990...and first SEC Championship game victory.
