Dalvin Cook is looking into switching from No. 33 to No. 4, the number he wore in high school and at Florida State.

There are expected to be several number changes with the NFL's loosened rules on uniforms.

According to an unnamed source, Cook "would love to go back to" No. 4, but that the Minnesota Vikings running back currently is "looking at the inventory costs."

Players who want to change for 2021 must purchase the unsold inventory. A change could currently be arranged for 2022, at no cost to the player.
