The Colts practiced without wide receiver Ashton Dulin (hamstring) and defensive end Arden Key (hamstring) on Thursday.
Neither player has practiced this week.
It does not bode well for their availability for Sunday’s game.
Linebacker Jaylon Charles (ribs) also has missed both practice days this week.
Center Tanor Bortolini (ankle) returned to practice with limited work Thursday, and linebacker Akeem Davis-Gaither (knee) was a full participant after not practicing Wednesday.
Wide receiver Keenan Allen (rest/groin) and cornerback Charvarius Ward (rest/groin) were limited a second consecutive day.
