LAKE FOREST, Ill. -- Chicago Bears wide receiver Alshon Jeffery was relegated to being a spectator Tuesday during the club's first day of minicamp due to a minor hamstring injury he suffered at a prior offseason workout.
Jeffery's on-field absence allowed second-year wideout Joe Anderson to get more reps with the first team.
"[Jeffery] ran a go-route the other day and made a great play out there and just tweaked it a little bit," Bears coach Marc Trestman said. "We're just going to be as cautious as we can. We're trying to get out of here with every player being healthy, and keeping our team as safe as we can amidst the competition that you see going on out there."
Jeffery caught 24 passes for 367 yards and three touchdowns in 10 games last season, missing a total of six weeks due to a knee injury and a fractured hand.
While Jeffery rested his hamstring, fellow wide receiver Brandon Marshall participated almost fully during Tuesday's session. Marshall took part in team drills Tuesday in front of the media for the first time this offseason. The Pro Bowler was limited to individual work last week at the Bears' final organized team activity as he continues to work his way back from offseason hip surgery.
Marshall anticipates being 100 percent when training camp opens late next month.
Meanwhile, 2012 first-round pick Shea McClellin participated fully in the opening minicamp workout despite a Chicago Tribune report that the defensive end has suffered from plantar fasciitis.
McClellin acknowledged dealing with the foot issue earlier in the offseason but said he is experiencing no discomfort and that he's able to practice without restrictions.
"It's gone right now," McClellin said. "I took care of it, and it's long gone. I feel great right now."
Players can be fined up to $66,150 for skipping the three-day mandatory minicamp. The Bears had near-perfect attendance Tuesday, with the exception of first-round pick Kyle Long, who by NFL rules cannot participate because of Oregon's final exam schedule.
However, Long is scheduled to arrive at Halas Hall next week for the NFL's rookie development program, which features a series of courses that are aimed at helping rookies transition to NFL life. Long can then use the Halas Hall facilities to train, if he chooses to do so, until the club reports to Bourbonnais, Ill., for training camp July 25.
