Middlesbrough moved into eighth place in Premier League 2 Division 2 with a goalless draw against north-east neighbours Sunderland.
Aside from a late disallowed effort for the hosts, there were few clear openings in a goalless draw at the Riverside Stadium.
Middlesbrough's fourth straight draw puts them above ninth-placed West Bromwich Albion, while Sunderland remain at the foot of the table.
