Most NFL fans recognize Adrian Peterson best in the No. 28 jersey that he wore at Oklahoma and during his best days with the Vikings.

However, Peterson has changed his number quite a bit over the years out of necessity. He will do that once again with the Titans.

Peterson isn't going to be wearing No. 28. Instead, he'll be wearing another new number, the fourth different one of his NFL career. He is taking advantage of the NFL's new number rules and it will be of the single-digit variety.

Below is more information about Peterson's newest numbers as well as all of the jerseys he has worn while playing for six different NFL teams.

What is Adrian Peterson's jersey number with the Titans?

Peterson will don the No. 8 jersey for Tennessee. It marks the first time during his career that he has worn a single-digit jersey.

The 36-year-old running back is taking advantage of the NFL's new jersey number rules. Running backs were only allowed to wear Nos. 20-49 under the NFL's previous jersey number rules. Now, they can wear any Nos. 1-49 and 80-89.
