The Ravens placed RB J.K. Dobbins (knee) on IR, knocking him out for at least the next 4 games. He's expected to be sidelined for 4-6 weeks after undergoing arthroscopic surgery on his knee, so landing on IR has no impact to his rest-of-season fantasy value. Dobbins is not a must-stash in shallower fantasy leagues. He probably won't be a starting option until December at the earliest.
