Robert Mathis

The Indianapolis Colts’ career sacks leader will serve as the IndyCar Grand Prix’s pace-car driver Saturday. The six-time Pro Bowler and 2013 NFL sacks champion announced his retirement at the end of last season. He finished his career with 123 sacks and one Super Bowl ring. Mathis has been a fixture in the Indianapolis community for more than a decade and still attends Pacers games. Mathis, former Pacers center Roy Hibbert and Pacers swingman Paul George have partnered to host an annual softball game that raises money for the Indiana Children’s Wish Fund. Mathis calls the pace-car duty a “bucket list” opportunity.
