The Angels placed Fulmer on the 15-day injured list Friday due to right elbow inflammation, retroactive to Aug. 27.
Fulmer allowed two runs and struck out eight batters over six innings during his last start Saturday, but he appears to have come away from the outing with elbow problems. He'll be forced to sit out until at least Sept. 11, and the 30-year-old may not have a rotation spot waiting for him when he returns -- the Angels are calling up top prospects Samuel Aldegheri and Caden Dana from Double-A Rocket City to bolster their rotation.
