Another fan wrote: "Rest In Peace Clark Haggans!"

Tributes continue to pour in

NFL fans have flooded Twitter to remember the late Steelers linebacker.

One fan wrote: "Clark Haggans' life was obviously so much more than one Super Bowl or the game of football.

"But he was a key piece to some great Steelers' defenses. Nine sacks in 2005, took down Matt Hasselbeck on the opening drive of SB 40.

"Rest in Peace, Clark."
