MANKATO -- Middle linebacker E.J. Henderson continued to gradually increase his workload in practice Friday and said his left leg has responded well.
"I still haven't taken anybody down fully to the ground yet so I'll be looking forward to that live contact," he said. "But we're going to take it slow. We're only in day No. 8. So keep trying to improve every day."
Vikings defensive coordinator Leslie Frazier said Henderson got 16 snaps in team drills on Thursday and 20 in Friday's morning session.
"We're gradually putting him in more and more situations and seeing how he responds and so far, so good," Frazier said. "He hasn't complained about any soreness or anything."
Frazier said it's still too early to tell whether Henderson, who broke his leg last December, will be ready for the season opener Sept. 9.
"It's hard to say," Frazier said. "We're just giving him a few more reps each day just to see what he can handle, but nobody really knows what's going to be the end point."
Henderson said he still thinks about his leg but it's not a mental hurdle.
"Not really totally out of mind," he said. "It's still cold so I've got to warm it up so of course I'm thinking about it. But as far as when I'm out there playing, it's all football and no thoughts about injuries."
