Chicago Bears wide receiver Luther Burden III is back on the practice field after missing most of the offseason program and the first four practices of training camp with a lingering hamstring injury. But the second-round rookie is already facing some adversity.

Ahead of Tuesday’s practice, head coach Ben Johnson discussed how the time that Burden missed with on-field reps after missing OTAs, minicamp and the beginning of training camp has impacted him.

“It shows up already,” Johnson said before Tuesday’s practice. “I mean, we were in the walk-through yesterday afternoon and the misalignments – we have to re-huddle, we have to start it all over again. He’s a little bit behind right now.”

That was evident on Tuesday, where Burden participated in team drills for the first time. Burden had some mental mistakes, including two different line of scrimmage penalties (according to Greg Braggs). One of those prompted Johnson to pull Burden out of a drill after he had trouble lining up in the right spot.

If you recall, Johnson did something similar with the starting offense on Day 1 of training camp. Meanwhile, the starting offense has cleared things up just five practices later. It just goes to show that Burden is already behind the rest of the offense after missing those valuable on-field reps.
