According to the Vikings' official website, Peterson announced Sunday on his "All Things Covered" podcast that he will wear No. 7, the same number he wore during his days at LSU.
The No. 7 was worn previously by 2020 seventh-round pick quarterback Nate Stanley.
As a result of the number change, Peterson will donate new shoulder pads to the football program at Menomonie High School in Wisconsin, Stanley's alma mater. The second-year QB will now wear No. 14.
Peterson, 30, signed a one-year, $10 million deal with Minnesota in March.
