Haren was reported of having lower back stiffness during his early season struggles. Weaver's decline in velocity over his last few starts (less than 4 K's in his last 4 starts) has been noted about. I don't think Weaver's injury tonight is just a random injury I think his decrease in velocity is related to his injury. My friend's I believe some lower back stiffness is just going through our two aces and that-hopefully-Weaver won't be out too long
