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.
Colvin (suspension) returned to practice Wednesday, Ryan O'Halloran of the Florida Times-Union reports.
Colvin was dealing with an ankle injury and had been sidelined since the team's preseason opener. He was back on the field Wednesday and should be available for Saturday's matchup with the Buccaneers. Colvin is suspended for the first four games of the regular season for taking performance enhancing substances, but he should be back to full strength by then.
Blackmon (suspension) was handed a one-year suspended sentence and probation Wednesday, stemming from a misdemeanor DUI, the Florida Times-Union reports.
Taken fifth overall in the 2012 NFL Draft by the Jaguars, Blackmon hasn't played in an NFL game since being suspended indefinitely back on Nov. 1, 2013 for a violation of the league's substance abuse program. Though he remains listed on Jacksonville's roster, the the 26-year-old wideout seems increasingly unlikely to play for the team again.
