Dulin (hamstring) has been ruled out ahead of Sunday's game against the Steelers.
Dulin likely sustained his hamstring injury in the Colts' Week 4 win over the Commanders. The wide receiver has not practiced since appearing on Wednesday's injury report with the issue and will likely need to miss some time. Deion Burks is set to be the No. 4 option at wide receiver in Dulin's absence.
