The Scottish midfielder has been made available by the Seasiders this season, but Mowbray has revealed that he is not interested in signing the 34-year-old.
"I really don't know where that's come from. An agent did enquire with me earlier this week and I told him 'no, there's no room in our midfield'. Barry Ferguson is a player that we enquired about last summer and it obviously didn't happen and he went to Blackpool," Mowbray told the Evening Gazette.
"We have got enough midfield players, as Nicky Bailey found out last night by not starting the game and Kevin Thomson is injured, so he didn't start the game. I know Barry Ferguson can only play centre midfield so I don't know where that's come from, it's never been in my thoughts.
"It's important for me to say that for the players we've got, Barry's not a player I'm trying to bring to the club."
A host of Championship clubs are understood to be interested.
