The Football Association has confirmed no formal disciplinary action will be taken against Emmanuel Adebayor over the incident involving Arsenal team-mate Nicklas Bendtner in the Carling Cup semi-final against Tottenham.
The pair squared up to each other in the second half of Tuesday's 5-1 Carling Cup semi-final second leg defeat against Tottenham.
However, the FA will write to both Gunners players to remind them of their responsibilities.
Referee Howard Webb failed to see the row, but the FA looked at video footage to decide on whether retrospective punishment was appropriate.
Adebayor had earlier apologised for the incident on the club's website.
"We are both passionate about this club, but it was a mistake. I am sorry," he said following the incident which left Bentner with a cut nose.
"We should have been more calm during the game and although I was pleased to get a goal back for the team when I came on, I am sorry for the disagreement with my team-mate Nicklas."
Arsenal were 4-1 down when the incident happened, and substitute Adebayor had been on the pitch for only 21 minutes.
The Togo international had made an impact on the game within eight minutes of his arrival when he scored Arsenal's only goal.
