Bears kicker Robbie Gould (quad) and safety Chris Conte (back) did not practice Friday and have been ruled out of Sunday's home game against the Detroit Lions.
Gould will be replaced by veteran Jay Feely for the third straight game. Since signing with the Bears Dec. 3, Feely has not attempted a field goal in back-to-back losses to the Cowboys and Saints.
It's not yet known whether Gould will play in the season finale a week from Sunday in Minnesota.
"It's week-to-week," said coach Marc Trestman. "He's certainly made the statement that he'll be out this week. He tried very hard to go last week, and it's not quite right. He wants to kick, so we'll see where he is next week. But obviously he's out this week."
Conte will be replaced by rookie Brock Vereen for the second straight week. Against the Saints, the fourth-round pick registered four tackles and forced a fumble that the Bears recovered two plays after Jay Cutler had thrown an interception deep in Chicago territory.
"That was a big play in the game," said defensive coordinator Mel Tucker. "[It was a] sudden-change situation. We talk about taking the field and putting the fire out and we did that. Brock was physical on the play. The ball was out and we fought to get it back."
Cornerback Tim Jennings (ankle), guard Kyle Long (hip) and defensive tackle Jeremiah Ratliff (knee) were all limited in practice and are listed as questionable. Defensive tackle Will Sutton (illness) did not work out Friday and is also questionable.
Cornerback Kyle Fuller (hand) and linebacker Shea McClellin (ankle) both practiced without restrictions and are probable for Sunday's game.
