Steichen confirmed that Dulin, who has been dealing with an ankle injury, will miss Week 2 and is listed as week‑to‑week, noting the receiver did not participate in practice this week.
The coach also said that Richardson, the team’s second‑string quarterback, missed Wednesday’s practice after a groin issue but should be available for Sunday’s game; Richardson reportedly tweaked the muscle while lifting weights earlier in the week.
Starter Daniel Jones remains the Colts’ primary quarterback, with rookie Riley Leonard now listed as the third‑string option behind Jones and Richardson.
Wide receiver Alec Pierce, who is recovering from a heel injury, was seen practicing on Friday after sitting out Thursday and appears to be on track to play in the Chiefs game.
Steichen added that Indianapolis will release its full injury report with official game‑day statuses later on Friday.
