Johnoson back at practice with Texans
Johnson sat out last week's workouts as a precaution after a ''mild strain'' of his groin on July 29. Johnson took about 20 repetitions Monday morning and said afterward that he felt no discomfort while running routes.
Brown hurt his left leg last Wednesday. The starter at left tackle for the past four seasons, Brown took his regular allotment of reps Monday morning.
Jackson strained his left hamstring a week ago. Coach Gary Kubiak says Jackson took ''half the reps'' in the morning and looked fine.
The Texans open preseason play at Carolina on Saturday.
