SANTA CLARA, CA—Following his team’s 24-10 win in Super Bowl 50, Denver Broncos quarterback Peyton Manning ended weeks of speculation surrounding his future by announcing Sunday that he has at least one more surgery in him. “I’ve had a long run and been a part of a lot of pretty big surgeries, but I still think I’ve got one more major operation left in the tank,” said Manning, adding that he had deliberated for the past six months with friends, family, and medical specialists before deciding that he wasn’t ready to hang up his hospital gown for good.
