Fuller (knee) underwent arthroscopic surgery this week and he is expected to miss several weeks, Dan Wiederer of the Chicago Tribune reports.
The Bears didn't specify which knee Fuller had scoped this week, but this is concerning news nonetheless for a player that's had a history of knee issues. The ominous "several weeks" timetable puts his status for Week 1 in question, which would leave the Bears down one of their starting corners for the opener against the Texans. If Fuller is unable to play in the opener, De'Vante Bausby or Deiondre' Hall would have to step up at the right corner spot.
Trevathan (hamstring) returned to practice on Wednesday.
Trevathan was forced from the Bears' second preseason game last week with the ailment, but it appears the team was simply being cautious with their prized free-agent acquisition. It's unclear whether he will take part in Chicago's third preseason contest on Saturday versus the Chiefs, though.
Miller (concussion) won't take the field for Thursday's preseason game at New England, Rich Campbell of the Chicago Tribune reports.
Miller has participated in recent practices, including Wednesday's walkthrough. However, inactive status Thursday implies that he remains in the concussion protocol and has yet to be cleared for any contact. With Miller sidelined, Khari Lee and Tony Moeaki should continue to receive reps with the first-team offense.
Royal (concussion) took part in practice Saturday, Jeff Dickerson of ESPN.com reports.
The concussion protocol has been Royal's home for the bulk of training camp and the preseason slate, but he's progressed from work on the side before Thursday's preseason game in New England to Saturday's appearance in practice. Although his activity level is unknown, he has clearly taken a step in the right direction in his quest to be cleared of symptoms.
Patterson had two receptions for 17 yards in Thursday's preseason win over Seattle. He missed Minnesota's first preseason game with a shoulder injury.
Patterson got time with the first-team offense and got to passes in the flat where he was able to use his speed to miss tackles. It was an encouraging sign that he could have a few plays a game designed for him on offense. However, his playing time is likely to be minimal on offense this season as he'll likely see almost all his action as a kick returner.
Heinicke (ankle) has shed the walking boot he wore to protect his foot from further injury, Scout.com reports.
Heinicke declined to talk about his injury after practice, reportedly saying it was time to go lift weights. If those were indeed his plans, his foot may be further along than anticipated. However, Shaun Hill has done nothing to relinquish his role as the backup to starter Teddy Bridgewater, and the Vikings project to carry only two quarterbacks on their active roster entering the regular season. Ultimately, Heinicke appears destined for either the practice squad or injured reserve list in 2016.
