Pompey fans have been allocated 4,200 tickets, a reduction of the 15% of St. Mary's' total ground capacity that Saints were supposed to allocate due to increased segregation.
It's believed that anyone who went to Coventry for the FA Cup third round replay will be guaranteed a ticket for the match (although how Pompey are going to work out who purchased tickets at the Ricoh Arena on the day is anybody's guess.)
After that, it's expected that the rest of the tickets will be served on a first-come, first-served basis to season ticket holders.
