Iron man (sports streak)

An Iron man is an athlete of unusual physical endurance. This durability is generally measured by an athlete's ability to play without missing a game and/or start for an extended period of time, sometimes, even for an entire career. Some of the more notable athletes with significant streaks in sports history includes baseball's Cal Ripken, Jr., American football's Brett Favre, basketball's A. C. Green, ice hockey's Doug Jarvis, and stock car racing's Jeff Gordon.
