Former Dallas Cowboys center John Fitzgerald, a two-time Super Bowl champion, is dead at 77.

The Cowboys' team website announced he died Tuesday morning. No cause of death was given.

In 1972, the team moved him to center, where he became a starter, and remained there until he retired. From 1973-80, Fitzgerald was the center for a Cowboys offense that finished in the top 10 in total yards in each of those eight seasons.
