Mack Lee Hill

Mack Lee Hill (August 17, 1940 – December 14, 1965) was an American football player, a running back at Southern University and for the American Football League's Kansas City Chiefs for two seasons (1964–65). He died suddenly after undergoing knee surgery, two days after a game against the Buffalo Bills.

Born and raised in Quincy, Florida, Hill made the Chiefs' roster in 1964 as a rookie free agent out of Southern University in New Orleans, signing for only $300, with an agreement he would only be paid he made the lineup. He wound up as the team's second-leading rusher that season with 567 yards and four touchdowns on 105 carries. Hill played in the AFL All-Star Game after his rookie campaign. He gained 627 yards, second-most on the team, in 1965, even though he did not complete the season, dying in knee surgery after the 12th game. He was nicknamed "The Truck."

Hill tore a ligament in his right knee in the regular season's penultimate game against the Bills on December 12, forcing him to undergo season-ending surgery on that knee two days later at Menorah Medical Center in Kansas City. He was still on the operating table when his temperature suddenly spiked to 108 °F (42 °C), triggering severe convulsions, and he died 1½ hours after surgery. Doctors said he suffered a "sudden and massive embolism."

Team doctor Albert R. Miller said the embolism could have been caused by a fat globule breaking off and entering the bloodstream, or it could have been triggered by a severe reaction to the anesthesia.

Head coach Hank Stram said, "Mark Lee Hill was a fine gentleman and a great football player. He was probably one of the most unselfish players I have ever coached. He was completely dedicated to the team. Football was his life."

Through Hill's inspiration, the Chiefs created the Mack Lee Hill Award, which is given each season to the team's most outstanding rookie. His No. 36 jersey has been retired.

He had a son, Marzell Hill.
