Bayer 04 Leverkusen midfielder Kevin Kampl is set for a lengthy spell on the sidelines after being diagnosed with a fractured fibula.
The Slovenia international picked up the injury during his side's 1-0 defeat to Borussia Dortmund on Matchday 22 and missed the subsequent 3-1 loss at 1. FSV Mainz 05 on Sunday with what it was originally feared was just a muscular injury.
Further tests carried out on Monday revealed greater damage than first feared, with the lower part of Kampl's left leg placed in plaster. The 25-year-old has been an almost ever-present for Die Werkself this season, making 19 Bundesliga appearances following his arrival from Borussia Dortmund last summer.
Leverkusen welcome SV Werder Bremen in the Bundesliga on Wednesday.
