I'm not completely sure, but Martin's in Oxford may have it. They have the best selection of Alabama shirts I've seen anywhere, with the best prices. If you ever pass through, they are perhaps a half mile north of the primary Oxford exit on I-20 (I believe it's Highway 21). Headed north, go through the main intersection with Highway 78 and they are directly across from the mall on your left.
If I get by there, I'll look for it.
