Uefa have confirmed the second leg of Celtic's Champions League clash against AC Milan will take place in the San Siro.
Capacity for the March 7th encounter will be limited but 4,500 seats will be reserved for Hoops fans.
The San Siro does not meet safety requirements introduced after the death of a policeman in violence before the Sicilian derby between Catania v Palermo earlier this month but work has started to bring it up to scratch.
The capacity for the last-16 tie is yet to be set and will be determined by the success in meeting the new guidelines.
A crowd of 21,000 Milan season ticket holders watched Milan beat Livorno on Sunday after 28 new turnstiles were installed.
However, more work must still be done before full capacity will be allowed at the venue.
Milan's rivals Inter will play their first knockout round first-leg match against Valencia next Tuesday at the San Siro. The permitted capacity for Inter's game will be 36,000, including 1,800 tickets for the Spanish fans.
Uefa was informed of the venue by the FIGC after the federation held talks with the Italian home affairs ministry.
