The team is preparing to move forward without Hicks for much of this season. The injury occurred eight plays into the Bears' loss to the Raiders at Tottenham Hotspur Stadium as teammate Khalil Mack struck Hicks' left elbow.
"We're hoping that he's definitely able to return here by the season's end," Nagy said during his regular appearance on WBBM Newsradio 780. "We'll find out exactly where that's at. That's our goal."
Second-year defensive lineman Bilal Nichols could help the Bears fill the void of Hicks. Nichols suffered a broken right hand in a win in Denver on Sept. 18. He had been nearing a return before the bye week.
The Bears are also ready to move forward without right guard Kyle Long, who has been playing through a hip injury. Long suffered the injury in September. He missed the team's win over the Vikings on Sept. 29 as a result but returned to play a week later. Long is expected to be placed on injured reserve, according to reports.
A three-time Pro Bowl lineman, Long has struggled while playing without optimal health this season. Veteran Ted Larsen would likely step into Long's starting spot.
"We want to credit him for battling through an injury," Nagy said. "It is a tough loss. But it's part of the game. We understand it. He understands it. And we just got to keep plugging away."
Nagy had no update on the status of quarterback Mitchell Trubisky, who missed the Oct. 6 game with a left shoulder injury. The Bears will be monitoring Trubisky's status during the course of this week.
The Bears return to practice at Halas Hall on Monday. They host the Saints (5-1) at Soldier Field on Sunday.
