morten Anderson nfl from 86 to 08
George Blanda Had 26 Years.
This is a very broad question. You might want to ask who had the longest career in NBA, MLB, MLS, NFL, and NHL ext. This will tell you who had the longest career in each sport and you will then be able to see who had the longest career or ( in your words) who played sports the longest.
Emmit Smith has the most career rushing yards in the NFL.
George Blanda he played 26 years in the nfl as a quarterback/kicker but 3 of those years he never threw a ball so he only played a QB for 23 years but is still the longest career as a QB.
Probably Brett Favre who is in his 19th or 20th year in the nfl and who now plays for the minnestota vikings
I think George Blanda is likely the player with the longest career.
The longest career in NFL history belongs to the great George Blanda. Blanda played 26 season as a kicker and quarterback for Oakland, Baltimore, Houston, and Chicago.
BenJarvus Green-Ellis has the longest streak of carries to start an NFL career without a fumble (589).
I BELIEVE GEORGE BLANDA OF THE OAKLAND RAIDERS HAD THE LONGEST NFL CARREER (WELL OVER 20 YRS.). Blanda played in the AFL (not the NFL) from 1960-1969. So you can take 10 years off of his total if you take the question literally. Correct answer for longest NFL career would be Morten Andersen. With 25 seasons and the NFL record for most games played at 382. Blanda is third on the list behind Andersen and Gary Anderson.
