LeGere: Bears shuffle the deck with receivers
Wide receivers Alshon Jeffery (hamstring) and Brandon Marshall (ankle) did not practice Wednesday inside the Walter Payton Center and Josh Morgan was limited with a groin injury.
That left one healthy receiver - Santonio Holmes - on the 53-man roster, although there are three wideouts on the practice squad: Josh Bellamy, Greg Herd and Rashad Ross.
Neither Jeffery nor Marshall was present during the portion of practice open to the media.
"They're in treatment today," said Bears coach Marc Trestman. "They're day to day. We'll be optimistic until we learn otherwise."
Since Marshall missed very little playing time Sunday in the season opener against the Bills, there is cause for optimism. But not so for Jeffery, who did not finish the game.
"We're moving personnel groupings around," Trestman said. "We can move things around and limit some of the receivers. Other times, we'll have them out there. But we got through practice."
Not happy returns:
With the release of wide receiver Micheal Spurlock, running back Senorise Perry is the only kickoff returner from this week's depth chart still on the roster; and wide receiver Santonio Holmes is the only punt returner.
Special teams coordinator Joe DeCamillis wasn't thrilled with the production last week in either phase.
The Bears returned just 1 of 6 Bills kickoffs, when Perry fielded the ball 8 yards deep in the end zone and only made it out to the 13-yard line.
"In my opinion, (there was) one returnable ball, and it wasn't the one we took out," DeCamillis said. "You've got to make good decisions."
Holmes' only punt return went for minus-1 yard.
"That was probably the most frustrating thing in that game," DeCamillis said. "Because, if you really watch the first return, (No.) 81 for them (Marcus Easley), I knew he was a hard matchup, and he made a great play. Santonio had a chance to get going on that one. The second one that he had to fair-catch, the same type of situation. We had a chance to get started well on punt return, and we didn't. We've got to really focus on that and make the most of those opportunities."
Safety dance:
The tandem of strong safety Ryan Mundy and free safety Chris Conte, who had the Bears' only interception in Week 1, is expected to remain intact. But Danny McCray will get some snaps in place of Conte.
"Chris and Ryan are going to get a brunt of the work, certainly," coach Marc Trestman said. "We rotated Danny in. Danny played well when he was in there. There will be times that we'll continue to move them around."
Other injuries:
Center Roberto Garza (ankle), guard Matt Slauson (ankle), fullback Tony Fiammetta (hamstring) and quarterback David Fales (shoulder) did not practice Wednesday and cornerback Charles Tillman (coach's decision) was limited.
Garza and Slauson are not expected to play Sunday against San Francisco.
Opening act III:
Sunday night will be the first regular-season game at the 49ers' new Levi's Stadium in Santa Clara and the third time since 1988 the Bears have played the first game in an opponent's new facility.
In 2008, the Bears whipped the Colts 29-13 in the first game at Indianapolis' Lucas Oil Stadium. Ten years earlier the Bears were beaten 27-15 by the Bucs in the first game at Tampa's Raymond James Stadium.
