Tony Romo wasn't on the field at the start of Cowboys' practice Friday, giving Jon Kitna another day of work with the starters.
Romo is dealing with a cracked rib and a lung that's recovering from a puncture. He hasn't practiced since leading Dallas to a comeback win over the 49ers on Sunday.
Coach Jason Garrett hasn't said whether Romo must practice before playing the home opener Monday night against Washington (2-0).
The Cowboys (1-1) have another practice Saturday and a walkthrough Sunday.
Receiver Dez Bryant returned Friday for the first time since injuring a thigh in the opener. Running back Felix Jones (shoulder) and center Phil Costa (knee) also returned after missing practice Thursday.
Receiver Miles Austin (hamstring) remains out.
