The Dutch winger has been out of action since pulling a hamstring during the Bavarians' 3-0 win over Wolfsburg in September.
"For Sunday, there's no way, because he has not trained with the ball and the team," Heynckes to AZ. "I hope that he'll be back training with the ball soon.
"He will possibly be available for the DFB-Pokal game against Kaiserslautern next Wednesday."
However, Heynckes did have some good news regarding striker Mario Gomez.
"He has trained very well. He came through pain free and I think that he could finish the first part of the final training session with the team on Saturday, but no one can forecast when he will be back in the squad."
Bayern are yet to lose domestically this season and sit top of the Bundesliga.
