"When I'm out there running now, I don't feel that pain anymore, so that's a good thing," Johnson told KILT-AM in Houston. "They say it could take up to six weeks at the most, but I don't think it'll take me that long."
Coach Gary Kubiak hasn't ruled Johnson out of Sunday's game at Tennessee, but the team's leading receiver said his hamstring is not at full strength.
"You really can't put a timetable on it, it's just whenever it feels back to normal," he said. "Right now, it's still weak. It's not as strong as it used to be. I still can't run full-speed yet, but I am out on the field running. I've tried to run full-speed, but I'm just taking it day by day."
