Up next for Dustin “The Diamond” Poirier is a co-main event scrap with Cub Swanson at UFC on Fuel TV 7. But before catching Poirier’s collision with Cub on February 16th, check out this pic spotted of the featherweight contender sporting the HEADRUSH “13 Crew” T-Shirt. We’ve seen Poirier wearing HEADRUSH during his past few walkouts including his most recent battle against Jonathan Brookins during the TUF 16 Finale. Siding with “The Diamond” when he faces Swanson later on this week? Check out the pic below and show your support by scooping up the official HEADRUSH Dustin Poirier Signature Shirt.
