Jets running back Chris Johnson (knee) was medically cleared recently by Dr. James Andrews to participate in training camp, reports ESPN. And he was back on the field Wednesday.
Coach Rex Ryan said Johnson was "flying" in the mandatory conditioning run. The Jets practice Thursday for the first time.
Johnson had surgery this offseason to repair a torn meniscus. As a precaution, the Jets kept him on the sideline in the spring.
"I'm pretty good," he said of his knee. "I'm ready to do whatever they ask me to do."
