Veteran manager Neil Warnock is set for a return to the game.
Many had believed Warnock was done with management, after the 71-year-old left Cardiff last month.
He had been in charge at Cardiff for the past three years.
Boro lost 4-0 to Leeds United in the Championship at the weekend, piling the pressure on the former central defender.
Warnock is somewhat of a specialist at getting clubs promoted to the Premier League, which would appeal to Middlesbrough.
He has previously been linked with a move to Scottish side Hearts.
