The Arsenal duo ended up in a car hijacking drama two weeks ago when knife-armed motorcyclists stopped the Mercedes they were both traveling in. Özil fled into a restaurant while Kolasinac challenged the perpetrators.
"Mesut Özil and Sead Kolasinac will not be in the team for our opening match against Newcastle United due to additional security incidents being investigated by police," Arsenal said in a statement on Friday.
"The safety of the players and their families is always a top priority and we have made this decision after talking with the players and their representatives".
