Jack Youngblood
In the 1979 playoffs, Youngblood, a linebacker for the Los Angeles Rams, fractured his fibula while sacking Dallas QB Roger Staubach. Not only did Youngblood finish that game, he also played though the injury in the NFC Championship Game and Super Bowl the following weeks thanks to a crude plastic cast he attached to his broken leg. Oh, Youngblood also played in the Pro Bowl the week after the Super Bowl. Yes, that’s right — the same meaningless game today’s athletes skip if they have so much as a hangnail, Youngblood played in with a broken leg.
