Japan forward Keisuke Honda will miss Friday's Kirin Cup game against Bulgaria with a left-knee injury and could also be out for the second match next week, coach Vahid Halilhodzic said Wednesday.

Halilhodzic made it clear he is not taking any risks with the AC Milan man, who has sat out training the last couple of days having developed pain in the knee.

After Japan plays Bulgaria, it faces either Denmark or Halilhodzic's native Bosnia-Herzegovina on Tuesday in Osaka.
