Cricket Australia might let Andre Russell use his black bat again, provided he can prove it will not mark the ball.
But officials have banned Russell's bat after he used it in the Tuesday night BBL Sydney derby.
The West Indian originally had permission to use the eye-catching bat, which has a pink handle and a black blade.
But that approval was withdrawn after match officials discovered the bat had marked the white ball.
"We have decided to withdraw our approval for Andre to use the bat that was used last night as the colour solution used by the manufacturer was discolouring the ball," BBL boss Anthony Everard said.
CA have not ruled out Russell being able to use a coloured bat again in the BBL.
"Should Andre, or any other BBL or WBBL player ... wish to use a bat with a different colouring solution to the one used last night that doesn't result in the discolouration of the match ball, they will be permitted to do so subject to CA being satisfied that the bat won't compromise the integrity of the game," Everard said.
Under BBL regulations, a player can use a coloured bat, subject to approval.
It must be black or the same as the team's primary colour.
Match umpires can also ask a player to change the bat if they feel it is affecting the integrity of the game.
Russell scored nine from seven balls for Sydney Thunder in their nine-wicket loss to the Sixers.
