Paea missed two games because of a toe problem, and the issue cropped up again in the first half. The Bears announced at the start of the third quarter he would not return.
Paea is active for Sunday's game against the Washington Redskins. Paea's return was a boost for a defensive line that has lost tackles Henry Melton and Nate Collins for the season with injuries.
Paea could return in Week 7 against Washington.
