Hertha Berlin will be without injured striker Marko Pantelic and his Serbian compatriot Gojko Kacar for Friday's Bundesliga clash at Arminia Bielefeld.

The team top scorer Pantelic is out with a knee injury while Kacar is struggling with an inflammed Achilles tendon. Hertha coach Lucien Favre also revealed Wednesday that club captain Arne Friedrich is doubtful due to a back problem.

Hertha currently lie second in the table, two points behind surprise leaders Hoffenheim, but if Friedrich is unavailable against his old club then Favre will be without 10 of his first team squad for the Bielefeld game.
