Colbert reiterated his stance from earlier this week that he won't trade Brown at a discount.
"If it doesn't benefit us, we won't do it," he said Friday.
Steelers owner Art Rooney II met with Brown on Tuesday. The receiver says they agreed it was best if the star moved on from the franchise.
Brown shared an Instagram Live video Monday declaring what he expects contractually from his next team.
"Tell them I ain't doing no unguarantees, I ain't even gonna play myself no more for this NFL," Brown said. " ... If your team got guaranteed money, tell them to call me."
