Jackson hasn't played since the season opener because of the hamstring and Wednesday was the first day he's practiced, albeit in a limited fashion, since the injury.
"Tomorrow is a good day to find that out and Friday is another good day," Jackson said. "As long as I can gradually get better, it's possible."
Jackson participated in individual drills but did not go more than perhaps 50-to-75 percent speed. When the other players were going through full-team work, Jackson said he was off to the side running routes, which he said left him feeling good about his progress. There was no need to do a lot of work on his first day back.
"I don't really have that pain anymore," Jackson said. "Just getting acclimated, getting that flow, getting that blood moving back in that area. ... It can't just happen in one day, it's my first day back out there. I definitely didn't try to push it to that limit. Day by day I'll be able to do more and do more reps."
