Aubameyang, who broke the deadlock at Selhurst Park, was shown a straight red card for his foul on Meyer.
Mikel Arteta says Pierre-Emerick Aubameyang's rash challenge on Max Meyer in their 1-1 draw against Crystal Palace on Saturday "looked nasty".
The Gunners boss believes the Gabon international had no intention to injure midfield star Meyer.
Aubameyang, who broke the deadlock with his 14th Premier League goal of the campaign in the 12th minute, received a red card in the 67th minute after a VAR review overturned the initial yellow card following his rash tackle on the Crystal Palace player.
"I just watched it and it looked nasty, to be fair," Arteta said after the draw at Selhurst Park. "Knowing Auba, there's no intention to make such a tackle.
"Hopefully he hasn't been injured and we are sorry for that. The decision was made and we have to accept it."
