Briggs, 46, back from doping ban, seeks oldest heavyweight crown

Two-time heavyweight champion Shannon Briggs announced a 2018 comeback Thursday after serving a doping ban, the 46-year-old American saying he will try to become boxing's oldest-ever heavyweight champion.

"I'm really happy to be getting back into training and I want to fight in 2018," Briggs said in a statement. "This past year was a tough year for me. It has been a long road, with many twists and turns, but I battled through it and feel good about the future."

Should he realize his goal, Briggs would become the oldest fighter to claim the crown in the elite division, surpassing George Foreman's feat at age 45.
