BT Sport has apologised to viewers after its coverage of the North London derby was interrupted during injury time.
Viewers watching on BT Sport were suddenly greeted by a blank screen, shortly followed by a message apologising for a technical error.
The action did resume some minutes later as the broadcaster instead switched to the Premier League's international feed, which had no audio.
In a statement about the incident, BT said: "We are sorry for the serious technical problem that affected today's live coverage from Tottenham. This was caused by a local power outage."
Neither side could ultimately find the net during time added-on and the match ended in a stalemate.
