Slayton (coach's decision) is inactive for Sunday's game against the Commanders in London.
Even though the Colts' depth at wide receiver will be tested in Week 4 with Keenan Allen (groin) inactive and Alec Pierce (heel) out for a second straight game while on injured reserve, Slayton apparently needs more time to get acclimated after signing with Indianapolis on Sept. 21. With Slayton being a healthy scratch, the Colts will proceed with Josh Downs, Laquon Treadwell, Ashton Dulin, Deion Burks, Nick Westbrook-Ikhine and Anthony Gould as their available options at wideout.
