How recent is the picture?
I find that often if a nike endorsed athlete is wearing a new shirt, it's from a collection that won't be released at retail or online for a few weeks or maybe even a couple months. Might be the case here too.
That is an old design that may be hard to find now? My buddy has one, but I think he got in back in 2011
If you can't find the Foley shirt... Just get a heather grey Nike golf shirt. And put a piece of electrical tape across the chest and diagonally across the right bicep. Problem solved.
