Shortly before the half time break in yesterday's Bundesliga clash between VfB and Leverkusen, Roberto Hilbert was injured in a challenge with Bayer striker Stefan Kießling. The German international returned for the rest of the first period after receiving treatment but had to be replaced by debutant Julian Schuster for the second period. Hilbert was suffering from ankle trouble and an examination on Sunday morning showed torn ligaments in the right ankle. The full-back will be unavailable for at least two weeks and out of Armin Veh's side until after the next international break.
