Coach Doug Pederson relayed that Ertz (ribs) will be out for Sunday's game against the Steelers.
On the plus side, Pederson added that he is prepared for Ertz to be ready to return to action after the Eagles' Week 4 bye. Trey Burton -- who logged a 5/49/1 stat line in Week 2 -- and veteran Brent Celek are thus in line to handle the Eagles' Week 3 tight end duties.
