Has a NFL player ever got injured in the Pro Bowl before playing in the Super Bowl?

Im a huge basketball fan, and I watched football as a kid but am just now starting to REALLY get into it as far as following a team (Cleveland Browns) and attending games. I just want to know has any player that was supposed to participate in the Super Bowl ever been injured during the Pro Bowl? Thw Pro Bowl this year is Jan. 30, and the Super Bowl is beginning of Feb. What happens if its Pats vs Packers and Woodson decides to level Brady? lol
