Jamaal Charles continues to truck his way further down the road to recovery, and he passed another major milestone this week: He participated in full-team drills for the first time since his injury.

JC returned to practice Aug. 16 and participated on a limited basis, running only during positional time before leaving the field for individual rehab work. Since then, the Chiefs have slowly upped the four-time Pro Bowl running back’s workload, and on Tuesday, he participated in full-team drills as his team prepares for its third preseason game Saturday against the Chicago Bears.

Head coach Andy Reid talked about Jamaal’s status, and that of linebacker Tamba Hali, who was just removed from the PUP list, for that game and for Week 4 of the preseason, and he said that they’ll continue to exercise caution when it comes to their veterans on the mend.

“Only if I feel if they’re right,” Reid said. “But I’m not going to stick them out there if there’s a question on it.”

JC saw an increase in his work this week, participating in 9-on-7 and 11-on-11 work with the team. Meanwhile, Week 3 of the preseason could mean a slight uptick in work for the first-team offense as it looks to prepare for the Sept. 11 season opener against the San Diego Chargers.

While the Chiefs are winless so far in their first two exhibition tilts, quarterback Alex Smith likes what he is seeing from the K.C. offense. The former Utah signal-caller explained how the young Chiefs had a coming of age moment last year without their security blanket at running back.

“It is really a compliment to Jamaal when I say: I feel like we got more complex when he was out,” Smith says. “Because Jamaal is such a freak player, he gets you out of stuff. When you run into bad looks, it doesn’t matter, because Jamaal will sometimes break those into his longest runs. I felt like we grew not being able to always lean on him.”
