Spurs’ trip to Orient last Tuesday was cancelled at the eleventh hour after a number of the home side’s players tested positive for Coronavirus.
The English Football League (EFL) have now announced Orient will have to forfeit the fixture, allowing Tottenham to advance to the fourth round at the expense of the League Two side.
Jose Mourinho is now set for a reunion with former employers Chelsea at the Tottenham Hotspur stadium next week after the Blues dispatched Barnsley 6-0 in the third round.
In a statement on Friday, the EFL said: "In accordance with Carabao Cup Rules, Tottenham Hotspur have been awarded with a bye to progress to Round Four of the Carabao Cup and will now play Chelsea on Tuesday 29 September.
"The Round Three tie scheduled for Tuesday 22 September between Leyton Orient and Tottenham Hotspur could not take place following the issue by Waltham Forest Borough Council of an order preventing the match being played as planned. This followed a number of Leyton Orient players testing positive for COVID-19.
"The EFL Board has determined that in line with Carabao Cup Rule 5.1, the Club was unable to fulfil its obligations to complete the fixture by virtue of the Council's order and shall therefore forfeit the tie."
