Tiki Barber has filed papers to come out of retirement and try to revive his NFL career, according to the running back's agent. Barber, who turns 36 in April, hasn't played since the 2006 season with the Giants. Tiki's brother, Ronde, recently signed a one-year deal for his 15th season with the Buccaneers. "After seeing my brother still have fun at our age, it reignited the fire," Tiki Barber told FOXSports.com. "I'm really looking forward to the challenge of seeing if I can get back to the level of where I was. I started working out again recently. It kind of shocked myself. I still had a lot of the strength I had before. I'm really looking forward to making a return."
