Bears practice report: Brandon Marshall, Alshon Jeffery among non-participants

The San Francisco 49ers will hit the practice field later this afternoon, but in the meantime, the Chicago Bears wrapped up their first practice session of the week. The Bears are dealing with several injuries, resulting in some important players not participating on Wednesday.

#Bears players who did not practice due to injuries today included Fales, Fiammetta, Garza, Jeffery, Marshall & Slauson.

Brandon Marshall played through the injury last week, and has said he will be ready for Sunday. Jeffery's injury sounds like a bit more of an issue. He injured his hamstring against the Buffalo Bills, and missed the fourth quarter and overtime. Hamstrings are always tough to figure out, so we'll see what his practice participation is like the next two days.

The bigger issue for the Bears is on their offensive line. Left guard Matt Slauson and center Roberto Garza both suffered high ankle sprains last week. A high ankle sprain often costs a player multiple weeks, so it seems unlikely either will play on Sunday. The Bears re-signed Eben Britton this week, and will likely have to activate rookie Charles Leno, after he was inactive last week.

The potential absence of Jeffery is important, but the absence of two starting offensive linemen is even bigger. The Bears line isn't spectacular by any stretch, but the injuries could open the door for the 49ers defensive front to find more success than it did last week. The team struggled against DeMarco Murray, although the big lead potentially lead to some of that. However, that combined with a limited pass rush will cost the 49ers if it happens against better teams.
