Abstract
We show that the torsion order of a knot in knot Floer homology gives a lower bound on the minimum number such that an oriented -tangle replacement unknots . This generalizes earlier results by Alishahi and the author and by Juhasz, Miller and Zemke, that is a lower bound for both the unknotting number and for , where denotes the bridge index of .
