Colts sign Tyler Scott and Ben Nikkel to the practice squad, while Tyler Kahmann exits. Scott brings special-teams value and speed from Chicago, with limited immediate WR upside behind a crowded room. Nikkel, Iowa State product, arrives as a core preseason special-teams piece who could spell depth on defense if ever elevated. Kahmann’s removal tightens a WR group already deep behind Pittman, Pierce, Downs, Mitchell, Dulin, and Gould, highlighting Colts’ preference for ST versatility and roster flexibility.
