Bees from Aberdeen

Hi there, wonder if anyone can help? Myself and 3 friends are intending visiting Griffin Park early next year, we live in and support Aberdeen. We are looking at 22/2 v Middlesbrough or 7/3 v Sheffield Wednesday. If we book flights now, they are quite cheap, of course being Scottish this is very appealing .Now with us flying down on the Saturday, we run the risk of these games being moved for tv, is this likely? Also, would it be fairly easy to get tickets for these matches?
