You should probably go ahead and buy tickets if you think you might be going to the game. The next couple of games or so are sellouts and tickets will be really hard to come by. I'm not sure what your alotment is for the game, but if it is a sellout, you should be able to find tickets on Beale Street from scalpers beforehand. If the game is a sellout though, those tickets will be $75+ apiece for the nosebleeds, so buy them at face value while you still have a chance.
