The attacker wants out from the Championship club and he is not afraid to burn bridges in order to get his move. Crystal Palace have been touted as a potential suitor.
The 26-year-old arrived from Aston Villa in 2017, but wants out as the club is not in the Premier League.
"There's no further news on Jordan - he's just not been here," Potter told BBC Sport.
"That tells you that he's not part of what we're trying to do, by his own actions.
"It's whether we can get a good enough deal for the club. Otherwise, that's going to be an interesting time for him."
