The Bayern Munich midfielder could be out for "two or three weeks" but hopes to be fit for a Champions League last-16 clash with the Gunners
Arturo Vidal's rib injury could sideline him for up to three weeks, placing the Bayern Munich midfielder in doubt to face Arsenal in the last-16 of the Champions League.
The Chile international sustained the problem in the Telekom Cup final on January 14, where Bayern defeated Mainz 2-1.
Vidal did start against Freiburg as the champions returned to Bundesliga action with a 2-1 success on Friday, but he could not complete 90 minutes and was forced off early in the second half.
