Kyle Fuller won't travel with the Bears when they head to New England this week because of knee soreness, head coach John Fox said at practice Sunday.
"You're concerned about anybody that's injured," Fox said. "But I think it's something he was kind of fighting through during the offseason, he's fought through in camp. We'll look at it a bit more in-depth and see how it materializes."
Fuller played in Thursday's preseason opener against the Broncos. He hasn't missed a game in his first two seasons with the Bears. Last year he defended nine passes and collected a pair of interceptions.
Fuller's absence in the secondary will give more time to defensive backs Jacoby Glenn, Deiondre' Hall, Bryce Callahan and De'Vante Busby.

"We liked (Glenn) last year. He was on the practice squad primarily," Fox said. "He's a young player that we saw improve as we went and i think he has done that and we'll see how he does in a game setting thursday night."
Hall, who the Bears selected in the fifth round of this year's draft, had a solid showing in his first contest, breaking up a pair of passes in the end-zone. He could be a player who pushes for early playing time this season.
"They determine that. You give them opportunities, see how they perform," Fox said. "I thought in (Hall's) first test he earned more time, and we'll see where that takes us."
The Bears will practice with the New England Patriots on Monday and Tuesday before their game Thursday, something Fox said gives playeres a different look with a game-like atmosphere.
"I think it's kind of a good experience, practice being on the road. Even though we've got a large number of people I think it's good competitive work," he said. "It's almost like a fifth preseason game."
