Glennon indicated no concern about losing his job on Thursday night after the game.
"I don't single out one position," Fox said. "I know there are a lot of people out there that enjoy that. There's 11 critical positions and we've got to do a lot of work on all 11 of them."
The Bears (1-3) resume play at Soldier Field on Oct. 9 against the Minnesota Vikings.
LAKE FOREST, Ill. (AP) — If there is a change coming at starting quarterback for the Chicago Bears, it will be after a weekend away from football.
Tight end Zach Miller said eliminating turnovers could go a long way toward reversing the Bears' fortunes, regardless of who the quarterback is.
Glennon called improvement his focus in practice next week rather than maintaining a job.
"I don't want to close or open any possibilities," Fox said.
"The No. 1 thing we obviously have to fix are the turnovers,Cheap NFL Jerseys China," Glennon said. "I'm not giving our team a chance when you turn the ball over like that."
Glennon has a passer rating of 76.9 and is 93 for 140 for 833 yards with four touchdowns along with five interceptions and three lost fumbles. He threw two interceptions against the Packers, lost a fumble on a sack and had another snap ricochet off his knee for a lost fumble.
"That's not my focus," Glennon said. "I'm going to watch this film,NFL Jerseys China, learn from my mistakes and look forward to improving myself as a player."
"Until that happens,Wholesale NHL Jerseys, you don't really know," Fox said. "I don't think you know and I don't even know."
A day after Thursday's 35-14 loss to the Green Bay Packers, coach John Fox called it too early to make announcements on removing starting quarterback Mike Glennon in favor of rookie Mitchell Trubisky or veteran Mark Sanchez.
Sanchez has been the No. 3 quarterback for the first four games. It's also possible he could be moved up to backup so a more experienced player would be available to replace Glennon if he struggles.
"It's understandable,Cheap NFL Jerseys Authentic, but we've been in positions to win games with Mike and then we've had two games in which we just didn't take care of the football," Miller said. "If we take care of the football, really, I don't think that (quarterback) situation's being brought up, know what I mean?"

"I think, as I've referenced,Cheap Jerseys From China, the quarterback gets a lot more credit and a lot more blame than they deserve," Fox said. "We're looking at everything and we're not in a big rush to do anything about it because we don't have a game until next Monday night."
Trubisky was drafted second overall and has yet to see action through four games. Fox called him a "young player" after the game and on Friday said it's difficult to say if he is ready to play.
