WATCH: "The greatest two yard run in NFL history" - Marion Barber III escapes entire defense for a two-yard run 

Following news of Marion Barber III's passing yesterday, the NFL mourns the loss of the former Dallas Cowboys and Chicago Bears running back.

The 38-year old was found dead yesterday by Frenso Police inside his apartment. The cause of his death is currently unknown.

One of the most memorable moments of his career was his two-year run against the New England Patriots.

In what looked certain to be a safety for the Patriots, Barber III was stuffed in the backfield. Tackle Flozell Adams pushed him backwards, and after somehow escaping, the running back started evading tackles left-and-right before bursting from the endzone to break more tackles for a two-yard gain.

It was arguably the best two-yard run in NFL history and the running back will always be remembered for his determination and grit displayed in that sequence.

The running back was drafted by Dallas in the fourth round of the 2005 NFL draft out of Minnesota.

He finished his career with 4,780 yards and 53 touchdowns. He had 1,156 carries in 99 games. He also caught 179 passes for 1,330 yards and six touchdowns. He played six seasons for the Dallas Cowboys while playing his last and only season with the Chicago Bears.
