Considering how much he uses his legs, the knee injury sustained by the Redskins' Robert Griffin III could have a devastating effect on his career. But several elite quarterbacks have rebounded immediately from severe injuries. Griffin's might be worse, but here are five.
5. Randall Cunningham (1991) ?»
The Philadelphia quarterback suffered a torn ACL in Week 1 but came back -- albeit with less mobility -- to lead the Eagles to the playoffs in 1992 and win the NFL comeback player of the year award.
4. Dan Marino (1993) » The Hall of Famer went down with a torn Achilles at 32. Marino returned to lead the Dolphins to the playoffs in 1994, winning the comeback player of the year award and making the Pro Bowl that year and the next.
3. Michael Vick (2003) » In an exhibition game, Vick fractured his fibula. He returned late in the year, and the next season Vick led the Falcons to the playoffs and made the Pro Bowl.
2. Tom Brady (2008) »
He had reconstructive surgery on his left knee after tearing his ACL and MCL in the 2008 season opener. Brady was named the 2009 comeback player of the year and has made the Pro Bowl in all four seasons since.
1. Peyton Manning (2011) »
He sat out the entire season after having neck-fusion surgery, returning this year to rank second with a 105.8 passer rating. He led the Broncos to 11 straight wins and the top seed in the AFC playoffs.
