Denver Post sports columnist Woody Paige reported the color change in his column on Monday.
A spokesman for the Broncos says no official decision has been made one way or the other on changing the team's primary jersey color, but did say a year's notice is required by the NFL for any type of change to a team's uniforms.
The Broncos say a number of fans chimed in this year calling for the team to go back to its orange uniforms after the team hosted an "Orange Sunday" at INVESCO Field at Mile High earlier this season against the New York Jets.
The team says it takes fan feedback into account with decisions like this and always welcomes comments from its fan base.
