JACKSONVILLE, Fla. | The Chiefs were happy enough with their running game their first time without the suspended Larry Johnson.</p><p> His main replacements, Jamaal Charles and Kolby Smith, combined to average more than 5 yards a carry.</p><p> The problem is that the Chiefs gave them the ball a total of only 10 times in a 24-21 loss to the Jaguars on Sunday. The game quickly became unbalanced for the Chiefs. They handed the ball to their running backs &mdash; including Dantrell Savage &mdash; 12 times while Matt Cassel threw 39 passes.</p><p> The Jaguars, who had been playing a 3-4 defense, surprised the Chiefs by playing mostly a 4-3.</p><p> &ldquo;It wasn&rsquo;t what we practiced against,&rdquo; Chiefs coach Todd Haley said. &ldquo;I thought for the most part we had an idea of what was going on.</p><p> &ldquo;(The offensive imbalance) was all predicated (on the defense). On a lot of our runs, there was a lot of pressure coming. They were bringing safeties from both edges, run blitzes we call them.</p><p> &ldquo;Average-wise, they were both pretty good. I feel like that&rsquo;s probably what they&rsquo;ll be. We need to hand the ball off more, and I think we would have gotten more out of them. I&rsquo;m encouraged by those guys.&rdquo;</p><p> Johnson is scheduled to return from his suspension today, but the Chiefs may opt to give at least some of his workload to Smith or Charles.</p><p> Smith hadn&rsquo;t played in a game in more than a year after last season&rsquo;s knee injury and the resulting surgery.</p><p> &ldquo;For Kolby, coming out of a long road back, there was going to be some rust,&rdquo; Haley said. &ldquo;We tried to rough him up at the end of the week on Thursday and kind of get him game-ready. To expect Kolby to lift the team on his shoulders would have been unreasonable. He got his feet wet, got some carries, got a couple of catches.&rdquo;</p><p> Smith started practicing last month and wasn&rsquo;t elevated to the active roster until Saturday. He had 17 yards in four carries and caught one pass for 4 yards.</p><p> &ldquo;I could definitely tell I had been away from the game,&rdquo; Smith said. &ldquo;I wasn&rsquo;t patient enough on some of my reads on the running plays. Obviously, game speed is different from practice speed. I was rushing things instead of being patient.</p><p> &ldquo;I took some big hits and that was good. Those got the cobwebs out of me. I didn&rsquo;t know how much I was going to play. Just playing any amount was good for me. I&rsquo;ll be ready for more next week if they need me.&rdquo;</p><p> Charles led the Chiefs with 36 yards in six carries, mostly perimeter plays and draws. The Chiefs again appeared hesitant to use him between the tackles.</p><p> &ldquo;We were going to go out there and run,&rdquo; Charles said. &ldquo;But we couldn&rsquo;t execute and we were going three and out. We started to throw the ball trying to make plays.&rdquo;
