The former Arsenal forward said he was sorry for letting the team down but maintains that his challenge was not malicious.
"I completely understand my sending-off changed the entire outcome of the game and I wholeheartedly apologise to my teammates, the manager and all the Tottenham fans," Adebayor said in The Sun.
"I must stress that my challenge was not malicious in any way. I was trying to win the ball and probably stretched my foot a bit too far in the heat of the moment.
"Nobody could have felt more devastated than me as I walked off the pitch."
The result meant that Arsenal moved above Spurs and into sixth in the Premier League table.
