Lake Forest, IL -- (Sports Network) - Chicago Bears wide receiver Brandon Lloyd is doubtful for Sunday's contest against the Atlanta Falcons due to a knee injury.

The 27-year-old wideout, who injured the knee in Week 4's 24-20 win over Philadelphia, sat out last Sunday's 34-7 blowout over Detroit and did not participate in practice at all this week.

In his first season with the Bears, the Illinois product has 15 receptions for 249 yards and one score.

In addition, Chicago has three players listed as questionable for the contest: defensive tackle Anthony Adams (ankle), linebacker Nick Roach (shoulder) and cornerback Nathan Vasher (wrist).
