Lucas Moura's header rescued Tottenham from an FA Cup upset in a 1-1 draw against Championship side Middlesbrough on Sunday.
Former Manchester United man Ashley Fletcher opened the scoring for the hosts in the second half but Moura scored the equaliser 11 minutes later to force a replay.
It is the first time a Jose Mourinho side has failed to win their opening FA Cup match at the first attempt.
There were very few chances in the first half but Paulo Gazzaniga made two fine saves from a goalmouth scramble.
The second half sparked into life when George Saville played in Fletcher who slotted the ball past Gazzaniga to shock the Premier League side.
Spurs responded well and equalised when Serge Aurier produced a fine cross for Moura to head home.
In Mourinho's 12 matches in charge since replacing Mauricio Pochettino, Spurs have kept only one clean sheet.
"At that moment I had the feeling of 'we are in trouble," Mourinho said. "But then everyone reacted. I reacted. The boys reacted. Giovani Lo Celso and Lamela helped us a lot.
"We managed to bring the game to our stadium. It's a game we don't need, our squad is short with so many problems -- but it's a game at home and we have to go for it."
